Purchased this as we have an Breathesmart 45i which we love. Fugured that this model had the air purity sensing and automatic fan speed control. Unfortunately it doesn't, all the settings are the same as on our other model, just manual. Still works well though. Purchased this as we have an Breathesmart 45i which we love.

Worth it? Not sure So I would so that I’m a picky sleeper. I cannot sleep with a fan on, but I can sleep with this on with no problem. The sleep mode is extremely nice with all the lights off. It seems to be helping with my boyfriend’s allergies to the dogs with a trial of about 3 months. The sensor has not told us to change the filter yet but we keep the dogs out of the bedroom so that is helpful.
Is it worth $400probably not but it gives my boyfriend a piece of mind so whateve
This is a 5star machine. However, the mfg sent a B4- Fresh filter we're as it should of been a B4-Pure filter (mold) as advertised and normally B4 Pure filter comes with this machine. I just received and open...very disappointed! This is a 5star machine.

Works great. Collected so much dust. I feel a difference after a month. Sleep mode is great. The lowest setting you can't even hear it. Turbo mode is great as well. I've tested smoking backwood with top shelf and it got the smell out in 30 minutes. Cord is decent length to move around. The lights turn off too Works great. Collected so much dust.

Who knows if these things work. Its expensive but it seems to work fine? My wife is happy and thats basically all I care about in this world. Maximum setting is kind of loud - we just run that at night and durning work - all other times we put it on minimum settings - they're easy to switch back and forth. Who knows if these things work.

My house has had a funky odor since we purchased it that we just could not identify. We paid a ridiculous sum of money to have work done in the crawl space, then we had the ducts cleaned, and we had the attic examined. A friend suggested an exorcism next! We still have no clue what caused the odor, but this fabulous air purifier did the trick. We are no longer assailed by the weird smell upon returning home from a long day out. We also sleep better and have fewer allergy symptoms (by far!). I now have one in both ends of the house. As an added bonus, we run both on full blast when we have indoor visitors from outside of our covid pod. This seemed to pay off in early January 2022 when someone symptomatic literally tested positive in the same room as one of the machines and no one else caught it. These machines are tallish, but attractive. I have both the stainless steel and a dark wood facing. They are flat enough to be placed nearish a wall, so they don’t take up a ton of space. It’s light and has a carry handle, so it easy enough to move it from bedroom to bedroom. They go completely dark when you hold down the button.

My daughter has had so many problems with allergies in her room. After buying this air purifier, I understand why she has those problems (See picture for reference) My husband and I know now that her window must not have a very good seal to it. We have only had the air purifier since August 20t which is only 4 months and this was all accumulated during that time. Im impressed! I threw away the other air purifier we were using in her room and will be buying a few more of these to spread throughout the home. Do your lungs a favor and buy this!

Life saver! After doing some digging on Reddit I was led to this air purifier & I am so glad I listened to the advice of that poster! For a while I thought I might have a heart condition as I was experiencing a lot of chest pains; it only vaguely occurred to me that it could be due to my asthma as it has never been this severe & not in congruence with my throat closing up. I hadn’t originally considered all the smoke & particles from the various fires we’ve had in California! We decided to give this a try just to be sure & within a week I felt better & the filter was THICK with black material!!! Amazing!
As long as you clean it regularly, I’m sure this filter will be a godsend to anyone like myself! I’ve noticed less dust, my asthma hasn’t been acting up, I’ve had ZERO chest pains, & the noise it makes is soothing & chill. The best part is that if you register the device through Allen & subscribe to their filter replacement subscription, you get a lifetime guarantee beyond the initial 1 year warranty!
As stated on their site:
“Provided that the unit is registered and enrolled in an active filter subscription withAlen, we warranty yourpurifier to be free from defects in materials or workmanship for the life of the unit.”
THIS ALEN AIR PURIFER DOES EVERYTHING IT STATES AND MORE. I HAVE A SMALL APT. (temporary-nursing student). I HAVE SEASONAL ALLERGIES AND A PET. THIS YEAR WAS ESPECIALLY BAD AND WAS THE REASON WHY I PURCHASED THIS SYSTEM. IT HAS MADE A REMARKABLE DIFFERENCE. IT IS QUIET (even on high the sound is not intrusive). I ESPECIALLY LIKE THE MEDICAL GRADE FILTER AND I ABSOLUTELY LOVE IT. I WOULD SUGGEST THIS PRODUCT TO ANYONE WHO HAS A SMALL SPACE (this unit accommodates 700 sq.ft), ALLERGIES/PETS.

These purifiers, that appear on the State of California's approved list of air purifiers, are really working well for us. We lower the fan speed at night on the purifier in the bedroom and it is quiet enough to allow us to sleep. If the smell ever gets bad, we run the fans on high speed and it takes care of it.

I live in a townhome with 4 connected units. The neighbors smoke and you can smell it through the vents. I've moved 4 times in 5 years due to neighbors smoking. This is the first purifier that helps. I still get a faint smell and possibly could control that if I moved the unit around. I'm thinking about purchasing a second unit for the upstairs. I live in a townhome with 4 connected units.

Last fall, we moved into an older 900 sq. ft. apartment that smelled like smoke, mold, and constantly has black dust everywhere. This thing has literally made the place smell better and keeps the dust to a minimum. I don’t cough now and my allergies are better. We’ve also got two cats and it collects a lot of their fur - and also grabs some of my hair too (long hair girl problems). Not to mention, IT IS SO QUIET! and pretty stylish. I love it.

Decent but expected more Update 8/15/2021 :
We’re doing a bunch of renovations at my house I’m currently at including taking up all the tile floor/ carpet and putting down vinyl floor. I vacuumed half to show how much it’s picked up in the past week. I have my original photo that I took after about two months but man I could definitely see the difference! This thing is grate for being around home renovations. The air definitely looked less cloudy like it did the first night before I had turned it on
Original :
All the reviews showed everyone’s filter picking up so much in so little time. After about 2 months the picture shows everything it got. Now it does save money by having the removable thingy that I can vacuum off to prolong the filter life! Very quiet thankfully my dog hates loud noises but it’s definitely quiet.
We first became aware of the Alen Air Purifier at our Optometrist's office. There was such a nice feeling of calm and clean air. Their office is above a busy parking lot. When we got home I immediately ordered one for our home as our bedroom is adjacent to our complex's parking garage entrance. The Alen Air Purifier has been a wonderful addition to literally make our bedroom a better place to enjoy - no longer are we bothered by the fumes of the cars that were leaking through our windows. My husband recently has had his immune system compromised so any help we can get in helping in a better environment is a blessing - thank you, Alen!

Game change I purchased this unit because the rental I was living in had a series of issues. The water heater broke, flooding my room. It took the landlords two weeks to authorize Servpro to come out, who took out a chunk of the wall, thus exposing me to all the mold that built up. I was suffering severe vertigo for about two weeks.
I purchased this filter, and by the following day, no congestion, no vertigo. It cleared the room of food or smoke odors in 15 minutes flat (roughly 350sqft room) and I couldn’t be happier.
Now that I am moved, I run it a few hours a day in the new place to keep things crisp. If it weren’t for a new mortgage payment, I’d buy two more!
I really like this device. It makes the sir feel cool and fresh. My wife is immune compromised so we bought it for her. Works well. I really like this device. It makes the sir feel cool and fresh. My wife is immune compromised so we bought it for her. Works well.
his is my third from Alen. the first one i bought - maybe a 6+ years ago, is still working. I have had no problems with any of them, and order new filters on their "auto ship" supply. overall, this one is better than the first 2 i bought (peralda/towers), as it's quieter and does bigger rooms. also, they seemed to have removed the uncertain "ion" mode feature with this newer version. I don't use that feature on my Peraldas that I have, but this one doesn't even offer the feature (which to me is an improvement because I was skeptical of the feature from the get-go). alen is easy to deal with, and never had any issue with getting new filters or with questions from them. his is my third from Alen. the first one i bought – maybe a 6+ years ago, is still working.

This is a very quiet machine compared to others I own. Simple to use, sleek design. Light weight, so Easy to move. It seems to be working on dust not sure about pet hair. Will be intetested in how long the filter lasts. Haven't had chance to test smells yet. This is a very quiet machine compared to others I own. Simple to use, sleek design.

We had to have this air purifier because of wildfires in Sonoma County. We are hoping this year isn’t as bad as last. We keep it running, it helps my allergies and keeps our air fresh.

This thing is great. We have this one and the 45i (class is with air sensor). Liked this so much bought one for a friend. Absence of sensor not a big deal. Smaller, quieter than the classic. Yes. You have to wash off the pre-filter about every month or two, but that allows you to go a half a year on a single filter. I live that I can even smell the clean air. And it has a light-off sleep mode, FYI. This is great. We move it from room to room and back and forth to my office. Very light. I love how it gets rid of dinner smell in our house which has great insulation and no circulation of fresh air otherwise when it is really cold or hot outside. This thing is great.

I bought this air purifier because I adopted a cat... and I am allergic to cats.... (my first mistake). So I would wake up completely stuffed up and pretty close to having an asthma attack. (I also have asthma... why I adopted a cat we will never know). One day I was tired of waking up literally unable to breathe through my nose so I started researching air purifiers on Amazon. This one had good reviews and I really liked the way it looked so I decided to give this purchase a try. BEST PURCHASE EVER. I have no issue's breathing anymore, my nose is never stuffed up anymore and I wake up feeling refreshed. My overall sleep quality has improved tremendously as well ( according to sleep tracking apps and my own body ). The purifier has a constant hum that is almost like a white noise machine, it's really soothing and helps me sleep. It isn't too loud or annoying. The air purifier is also great quality, I have tried blowing smoke into the air purifier and the smoke dissipates almost instantly. Whereas if I were to blow smoke (using incense sticks) into another area the smoke lingers. This really takes care of it all. My room has also started to smell nicer and just feel cleaner in general. The air purifier also looks great. I purchased the slate metal and it looks great in the room. My room is fairly large and it is able to take care of the dust , dander and smoke in my room.

WOW! What a great product. I looked at a lot of air purifiers before I purchased this Alen product. IT was a snap to set up. I had it operating in less than five minutes. And what a difference it makes. We live in a small (800 sf) apartment and could tell right away that it worked for us. We are keeping it running 24/7 for right now, since it is Spring and thestart of allergy season. WOW! What a great product. I looked at a lot of air purifiers before I purchased this Alen product.

I’m in love with this air purifier. It does the job and very well. I live in Tucson AZ and have lots of allergies. The system is easy to move around, light weight, quiet and easy to use. I was skeptical because there are so many systems out there. I have the system on all night I’m my bedroom and find the noise that it does make rather soothing, kind of like white noise. Yes it can be somewhat loud if on full speed but I use it at level 2 during the night. It’s super easy to use too. Highly recommend. I’m in love with this air purifier. It does the job and very well.

Bought two based on reviews and statistics, plus great price Amazon was offering. House seems a lot less dustier, and I believe the air is cleaner. Stats indicate that it will filter particles as small as a virus. We have had no illnesses since starting them up four months ago.

Quiet and looks good in the living room. Easy to set up and it actually works. Mother’s allergy reactions and symptoms have subsided. No matter how clean I kept the house she reacted to the invisible allergens in the air. This obviously removes those particles and I highly recommend for everyone wanting clean air in their homes.

This air purifier is the best money I ever spent. I’ve never slept better. The noise level is low and gives off just enough white noise to help you sleep.

Helping with ASTHMA + ALLERGIES! Also one of the better looking air purifiers out there. If you are thinking of getting the Alen FLEX air purifier to help with allergies or asthma or pets, read on (because I have all 3):
For context, I had been having worsening asthma and allergy attacks over the past few months, to the point where my asthma went from being predominantly exercise or allergy induced to recurring several times a day. After a trip to an asthma and allergy specialist and receiving a full allergy test, I was told that I was allergic to almost everything (every tree, grass and weed, dust mites, cockroaches, cats, dogs, etc. plus other food and miscellaneous allergies). I already knew I was allergic to all of those things but the doctor confirmed that I was on the “severe” end of the scale and I was advised to get rid of our cats and get an air purifier.
As most cat owners know, getting rid of a beloved cat would be like throwing your child out on to the street, so the cats had to stay even if it meant using inhalers twice a day, popping allergy medication daily and maybe just banning the cats from the bed and wardrobe. But we knew we would need a GREAT air purifier to help with all the allergens coming from our furry friends and everything else permeating our allergen-laden Northeast American air. You know how some people have “spring allergies”? I have spring, summer and fall allergies thanks to the wide range of trees, grass, and weeds that all decide to pollinate at different times.
I had been obsessed with getting a Molekule for a while, and if not, a Dyson. But to be entirely honest, neither was in our current budget due to a recent influx of life expenses. My husband and I agreed that getting a second air purifier from one of those brands might be in the cards when we move into a bigger home in a year, but for now, I should buy the best possible air purifier in the $300 range to cover 700-800 square feet.
After days of research and reading hundreds of reviews, I finally settled on this Alan FLEX purifier in Oak.
It’s a beautiful air purifier, and if you have a home with a more natural aesthetic like we do, the “wood” front helps the machine blend in more with its surroundings instead of sticking out like a sore thumb. We tend to like wood, natural fibers, ceramics, etc. for our decor, and I wanted a purifier that was barely noticeable at a glance because it somewhat camouflaged with its surroundings. Because it has such a minimalist design with clean lines and few obvious vents or mechanical-looking parts, I feel it would blend well with most decor schemes, and it’s so great that this model also has numerous colors and wood types to choose from.
As for how well it works, I could not confirm its effect on my health immediately but 3 weeks later, I absolutely noticed a reduction in the frequency of my asthma attacks. While I was having several attacks a day, I now have one every 2 to 3 days, and my health in general is improving with each passing week. With cats in the house, things are never going to be 100 percent perfect in that department but this air purifier has made significant improvements. I also wake up a lot less with puffy red eyes or a scratchy throat.
For the price point – neither cheap nor extremely expensive, I honestly do feel that Alen FLEX may be the best (if not, one of the best) options on the market, and is a wonderful combination of effectiveness and good design.
On the downside? It can be a bit loud when on the highest setting, which may be an issue for those interested in placing it in the bedroom like we do. Not overly loud but it depends on your personal opinion/perception of what constitutes “loud” for such a machine. Personally, I don’t really notice the noise anymore – it’s almost like white noise in the background. And I think that if it’s bothersome at night, you can put it on the low setting, which significantly reduces the noise when you sleep.
Works great ! my Chinese neighbors under me were cooking fish again the smell went right away plus it’s easy to carry around the house , and at night I put it on high speed for a soft background noise to sleep too Works great ! my Chinese neighbors under me were cooking fish again the smell went right away plus it’s easy to carry around the house , and at night I put it on high speed for a soft background noise to sleep too
Great air purifier but no instructio I needed a great house filter to get rid of kitty litter box smell. I have been using it set on high for about a month, and it apears to be doing the trick.
Large unit. But very quiet. Sheltering with covid , inside too much and is also cleaning all the air and removing stuffiness.
BUT — where are the instructions on installing the filter???? Do not know if the black sheet with filter. On or off unit? 8 took it off. Still works great .
After running initially on turbo for an hour than a week on low setting 24/7 the prefilter pictured here shows how much dust and pet dander was collected. Usually dust/vaccuum our home every 2 days but no dust after a week. So easy to vacuum the prefilter so your filter lasts longer. Barely audible on low. Simple to use. Glad I did the research and landed on Alen-best in class. Get your money’s worth!

Just wish it ran 24/7. Every 12 hrs I have too turn it back on. I keep it on level 2 (it has 4) due to sound. Just wish it ran 24/7. Every 12 hrs I have too turn it back on. I keep it on level 2 (it has 4) due to sound.

Good product, but supplier forces buyer to provide credit card to register the product for warranty This air purifier is pretty quiet and easy to operate. I ordered an extra filter at the same time so I do not have to worry about it when the filter is out.
What is very disappointing is when I tried to register the product for the warranty using the card the supplier provided, it asked me to provide a credit card for auto ordering filters. It did not give any option to register the product without providing a credit card. This is terrible customer service and a lousy marketing trick. I suggest suppliers change this approach and let customers choose to buy from there based on the quality of the product, service, and value.
Love this thing - it is so much quieter than the other four brands of air filters that we have in our home. Works really well. Looks great too. Love this thing – it is so much quieter than the other four brands of air filters that we have in our home. Works really well. Looks great too.

I really like this air purifier. It has a sharp, clean look. It is quiet and I really have noticed less dust in the living area where it lives now. I really like this air purifier. It has a sharp, clean look. It is quiet and I really have noticed less dust in the living area where it lives now.
This is between a 4 and 5 star product for me. This is the sixth Alen I have bought since October. I gave my mother this one for Christmas. Amazon had a deal on an open box with a smoke filter and it was too good to pass up. The Flex uses the same filters as the 45i including the heavy smoke filter with over 2 lbs of active carbon. My air is already almost always clear of PM 2.5 with as many filters as I have in my house. What was a little high was HCHO and TVOC. Most people would want these filters for wildfire smoke, for me cooking odors and chemical reduction is a priority. Most people shopping for this purifier are comparing it to the 45i. Their is about a $100 difference between them. For that the 45i gets wifi, auto mode, an ionizer, and a little more CADR. Ionizers are a hotly debated topic on here and I only use mine before I vacuum to collect a little more dust. I do love the Flex and my mother does not need to have her purifier on the internet. So my best advice to you is to buy either one if it comes on sale in your color. The 75i is a true workhorse, but even on sale is much more expensive. This is between a 4 and 5 star product for me.

This product works very well on getting rid off smoke smell. We bought this for my daughter because the tenant below her floor is a heavy smoker. The smoke came in from the front door and triggered her asthma and it got worsen. She has been using this product for almost two months and she felt much better. She does not complain the smoke smell in her apartment anymore. I will give it 5-stars. This product works very well on getting rid off smoke smell.

I have five different air purifiers in my house, one in every major room. I tend to buy ones that have at least 4.3 stars and only when they are on sale. I'm going to compare this air purifier to the I have five different air purifiers in my house, one in every major room. I tend to buy ones that have at least 4.3 stars and only when they are on sale. I’m going to compare this air purifier to the Blueair Blue Pure 121 since it was the last one I had in my 600 square foot living room. They both move a lot of air but the Alen tends to be a bit quieter at each speed. Perfectly timed for this review, my dog is due for a bath (happening tomorrow!) so I can confirm that both the Alen and the Blueair clear the room of pet odors. When I turned the Blueair off for a bit before installing the Alen, the room began to smell like the dog a bit. It was especially noticeable when leaving the room for a bit and coming back in. I was mortified, but thankfully thanks to Covid, nobody from outside the home would have smelled it. 🙂
The Alen quickly cleared the room of the smell on medium speed. It is relatively quiet at that speed, quiet enough to not have to increase the volume on the TV. I noticed that it was doing such a good job, that it was even sucking in some propane smell from my propane heater stove at anything higher than medium. So I leave it at medium since the volume level and performance are perfect for my room.
You can get a lifetime warranty on the Alen if you register it on their website and sign up for recurring delivery of one of their air filters. I opted to do so, especially since the air filters were the same price on the website as they were on Amazon. There are four air filters to choose from (see This listing on Amazon for the four options). They currently range in price from $69 to $119 depending on your needs. They are a bit expensive but if they work and only require replacement every 12 months, I guess they are worth it, right? I’d love to be able to test how each performs but I am going to stick with the one that works best for me without going overboard and that may be the second level one since there are no smokers in the house.
I am happy with the Alen so far. If anything changes, I will update my review. In the meantime, it is still going strong.
I suffer from allergies and could feel the difference in my home using this right away. I am also very impressed with the length of the time the filters last. Well worth the investment if you want to breathe clean fresh air! I suffer from allergies and could feel the difference in my home using this right away.

This machine is amazing. I have had what I thought was a sinus infection and I received my Allen room air filter two weeks ago and I no longer have a stuffy and drippy nose. I had a dust allergy. It’s amazing how that machine has cleared my bedroom of the dust. I’ve definitely noticed hardly any dust on the furniture . I highly recommend this room air filter.. This machine is amazing.

From the outer design to the inner design to the functionality design this thing is very impressive. Very well thought out down to even minor details that make a difference. This is easily the Air Purifier that Apple would make. Without the Apple price tag. From the outer design to the inner design to the functionality design this thing is very impressive.

This air purifier is a real gem. The filter is easily changed and lasts for months. It is very quiet and we noticed major difference in air quality in minutes. I highly recommend. We bought this one for upstairs where are bedrooms are. We are going to get a second one for downstairs. You won’t be disappointed with this fine Air Purifier. This air purifier is a real gem.

I just ordered this air purifier as we have 4 pets and lots of allergens in this house. The package arrived here in rough shape but the air purifier itself looked great! Still early on, but I am impressed how much cleaner the air feels now since I have plugged it in. Stay posted! I will give an update on a week. So far, so good!

My husband bought two of these, one for the living room and one for our upstairs bedroom which is quite large. The finish goes well with our living room decor. We did notice a decrease in tiny feathers from our pillows, cat hair and dust in our bedroom. Our baby is sleeping with us and she was getting stuffy nose from all the dust. She seems to be doing better. It’s pretty quiet on the lowest setting and at its loudest sounds like a white noise machine. Overall we are still liking this air purifier.

Purchased this as we have an Breathesmart 45i which we love. Fugured that this model had the air purity sensing and automatic fan speed control. Unfortunately it doesn't, all the settings are the same as on our other model, just manual. Still works well though.

Worth it? Not sure
So I would so that I’m a picky sleeper. I cannot sleep with a fan on, but I can sleep with this on with no problem. The sleep mode is extremely nice with all the lights off. It seems to be helping with my boyfriend’s allergies to the dogs with a trial of about 3 months. The sensor has not told us to change the filter yet but we keep the dogs out of the bedroom so that is helpful.
Is it worth $400probably not but it gives my boyfriend a piece of mind so whateve
This is a 5star machine. However, the mfg sent a B4- Fresh filter we're as it should of been a B4-Pure filter (mold) as advertised and normally B4 Pure filter comes with this machine. I just received and open...very disappointed!

Works great. Collected so much dust. I feel a difference after a month. Sleep mode is great. The lowest setting you can't even hear it. Turbo mode is great as well. I've tested smoking backwood with top shelf and it got the smell out in 30 minutes. Cord is decent length to move around. The lights turn off too

Who knows if these things work. Its expensive but it seems to work fine? My wife is happy and thats basically all I care about in this world. Maximum setting is kind of loud - we just run that at night and durning work - all other times we put it on minimum settings - they're easy to switch back and forth.

My house has had a funky odor since we purchased it that we just could not identify. We paid a ridiculous sum of money to have work done in the crawl space, then we had the ducts cleaned, and we had the attic examined. A friend suggested an exorcism next! We still have no clue what caused the odor, but this fabulous air purifier did the trick. We are no longer assailed by the weird smell upon returning home from a long day out. We also sleep better and have fewer allergy symptoms (by far!). I now have one in both ends of the house. As an added bonus, we run both on full blast when we have indoor visitors from outside of our covid pod. This seemed to pay off in early January 2022 when someone symptomatic literally tested positive in the same room as one of the machines and no one else caught it. These machines are tallish, but attractive. I have both the stainless steel and a dark wood facing. They are flat enough to be placed nearish a wall, so they don’t take up a ton of space. It’s light and has a carry handle, so it easy enough to move it from bedroom to bedroom. They go completely dark when you hold down the button. This is the best investment I’ve made for my family in a long time.

My daughter has had so many problems with allergies in her room. After buying this air purifier, I understand why she has those problems (See picture for reference) My husband and I know now that her window must not have a very good seal to it. We have only had the air purifier since August 20t which is only 4 months and this was all accumulated during that time. Im impressed! I threw away the other air purifier we were using in her room and will be buying a few more of these to spread throughout the home. Do your lungs a favor and buy this!
Life saver!
After doing some digging on Reddit I was led to this air purifier & I am so glad I listened to the advice of that poster! For a while I thought I might have a heart condition as I was experiencing a lot of chest pains; it only vaguely occurred to me that it could be due to my asthma as it has never been this severe & not in congruence with my throat closing up. I hadn’t originally considered all the smoke & particles from the various fires we’ve had in California! We decided to give this a try just to be sure & within a week I felt better & the filter was THICK with black material!!! Amazing!
As long as you clean it regularly, I’m sure this filter will be a godsend to anyone like myself! I’ve noticed less dust, my asthma hasn’t been acting up, I’ve had ZERO chest pains, & the noise it makes is soothing & chill. The best part is that if you register the device through Allen & subscribe to their filter replacement subscription, you get a lifetime guarantee beyond the initial 1 year warranty!
As stated on their site:
“Provided that the unit is registered and enrolled in an active filter subscription withAlen, we warranty yourpurifier to be free from defects in materials or workmanship for the life of the unit.”
THIS ALEN AIR PURIFER DOES EVERYTHING IT STATES AND MORE. I HAVE A SMALL APT. (temporary-nursing student). I HAVE SEASONAL ALLERGIES AND A PET. THIS YEAR WAS ESPECIALLY BAD AND WAS THE REASON WHY I PURCHASED THIS SYSTEM. IT HAS MADE A REMARKABLE DIFFERENCE. IT IS QUIET (even on high the sound is not intrusive). I ESPECIALLY LIKE THE MEDICAL GRADE FILTER AND I ABSOLUTELY LOVE IT. I WOULD SUGGEST THIS PRODUCT TO ANYONE WHO HAS A SMALL SPACE (this unit accommodates 700 sq.ft), ALLERGIES/PETS.

These purifiers, that appear on the State of California's approved list of air purifiers, are really working well for us. We lower the fan speed at night on the purifier in the bedroom and it is quiet enough to allow us to sleep. If the smell ever gets bad, we run the fans on high speed and it takes care of it.

I live in a townhome with 4 connected units. The neighbors smoke and you can smell it through the vents. I've moved 4 times in 5 years due to neighbors smoking. This is the first purifier that helps. I still get a faint smell and possibly could control that if I moved the unit around. I'm thinking about purchasing a second unit for the upstairs.

Last fall, we moved into an older 900 sq. ft. apartment that smelled like smoke, mold, and constantly has black dust everywhere. This thing has literally made the place smell better and keeps the dust to a minimum. I don’t cough now and my allergies are better. We’ve also got two cats and it collects a lot of their fur - and also grabs some of my hair too (long hair girl problems). Not to mention, IT IS SO QUIET! and pretty stylish. I love it.

Update 8/15/2021 :
We’re doing a bunch of renovations at my house I’m currently at including taking up all the tile floor/ carpet and putting down vinyl floor. I vacuumed half to show how much it’s picked up in the past week. I have my original photo that I took after about two months but man I could definitely see the difference! This thing is grate for being around home renovations. The air definitely looked less cloudy like it did the first night before I had turned it on
Original :
All the reviews showed everyone’s filter picking up so much in so little time. After about 2 months the picture shows everything it got. Now it does save money by having the removable thingy that I can vacuum off to prolong the filter life! Very quiet thankfully my dog hates loud noises but it’s definitely quiet.
We first became aware of the Alen Air Purifier at our Optometrist's office. There was such a nice feeling of calm and clean air. Their office is above a busy parking lot. When we got home I immediately ordered one for our home as our bedroom is adjacent to our complex's parking garage entrance. The Alen Air Purifier has been a wonderful addition to literally make our bedroom a better place to enjoy - no longer are we bothered by the fumes of the cars that were leaking through our windows. My husband recently has had his immune system compromised so any help we can get in helping in a better environment is a blessing - thank you, Alen!

Game change
I purchased this unit because the rental I was living in had a series of issues. The water heater broke, flooding my room. It took the landlords two weeks to authorize Servpro to come out, who took out a chunk of the wall, thus exposing me to all the mold that built up. I was suffering severe vertigo for about two weeks.
I purchased this filter, and by the following day, no congestion, no vertigo. It cleared the room of food or smoke odors in 15 minutes flat (roughly 350sqft room) and I couldn’t be happier.
Now that I am moved, I run it a few hours a day in the new place to keep things crisp. If it weren’t for a new mortgage payment, I’d buy two more!
I really like this device. It makes the sir feel cool and fresh. My wife is immune compromised so we bought it for her. Works well.

his is my third from Alen. the first one i bought – maybe a 6+ years ago, is still working. I have had no problems with any of them, and order new filters on their “auto ship” supply. overall, this one is better than the first 2 i bought (peralda/towers), as it’s quieter and does bigger rooms. also, they seemed to have removed the uncertain “ion” mode feature with this newer version. I don’t use that feature on my Peraldas that I have, but this one doesn’t even offer the feature (which to me is an improvement because I was skeptical of the feature from the get-go). alen is easy to deal with, and never had any issue with getting new filters or with questions from them.
This is a very quiet machine compared to others I own. Simple to use, sleek design. Light weight, so Easy to move. It seems to be working on dust not sure about pet hair. Will be intetested in how long the filter lasts. Haven't had chance to test smells yet.

My allergies have significantly decreased due to running this in the bedroom. Also, fan noises usually bother me, but the pink noise truly is soft background noise - it doesn't bother me at all!

We had to have this air purifier because of wildfires in Sonoma County. We are hoping this year isn’t as bad as last. We keep it running, it helps my allergies and keeps our air fresh.

Sleek design, not too big and not bulky and very quiet. We keep in one room usually but easy to move.

This thing is great. We have this one and the 45i (class is with air sensor). Liked this so much bought one for a friend. Absence of sensor not a big deal. Smaller, quieter than the classic. Yes. You have to wash off the pre-filter about every month or two, but that allows you to go a half a year on a single filter. I live that I can even smell the clean air. And it has a light-off sleep mode, FYI. This is great. We move it from room to room and back and forth to my office. Very light. I love how it gets rid of dinner smell in our house which has great insulation and no circulation of fresh air otherwise when it is really cold or hot outside.

I bought this air purifier because I adopted a cat… and I am allergic to cats…. (my first mistake). So I would wake up completely stuffed up and pretty close to having an asthma attack. (I also have asthma… why I adopted a cat we will never know). One day I was tired of waking up literally unable to breathe through my nose so I started researching air purifiers on Amazon. This one had good reviews and I really liked the way it looked so I decided to give this purchase a try. BEST PURCHASE EVER. I have no issue’s breathing anymore, my nose is never stuffed up anymore and I wake up feeling refreshed. My overall sleep quality has improved tremendously as well ( according to sleep tracking apps and my own body ). The purifier has a constant hum that is almost like a white noise machine, it’s really soothing and helps me sleep. It isn’t too loud or annoying. The air purifier is also great quality, I have tried blowing smoke into the air purifier and the smoke dissipates almost instantly. Whereas if I were to blow smoke (using incense sticks) into another area the smoke lingers. This really takes care of it all. My room has also started to smell nicer and just feel cleaner in general. The air purifier also looks great. I purchased the slate metal and it looks great in the room. My room is fairly large and it is able to take care of the dust , dander and smoke in my room. My allergies and lungs are very happy with this purchase.
WOW! What a great product. I looked at a lot of air purifiers before I purchased this Alen product. IT was a snap to set up. I had it operating in less than five minutes. And what a difference it makes. We live in a small (800 sf) apartment and could tell right away that it worked for us. We are keeping it running 24/7 for right now, since it is Spring and thestart of allergy season.

I’m in love with this air purifier. It does the job and very well. I live in Tucson AZ and have lots of allergies. The system is easy to move around, light weight, quiet and easy to use. I was skeptical because there are so many systems out there. I have the system on all night I’m my bedroom and find the noise that it does make rather soothing, kind of like white noise. Yes it can be somewhat loud if on full speed but I use it at level 2 during the night. It’s super easy to use too. Highly recommend.

Bought two based on reviews and statistics, plus great price Amazon was offering. House seems a lot less dustier, and I believe the air is cleaner. Stats indicate that it will filter particles as small as a virus. We have had no illnesses since starting them up four months ago.

I love this air purifier. It is very quiet on the lowest setting. It looks sleek and blends in with the decor. It is quite large, so make sure you look at the measurements before you buy it.

Quiet and looks good in the living room. Easy to set up and it actually works. Mother’s allergy reactions and symptoms have subsided. No matter how clean I kept the house she reacted to the invisible allergens in the air. This obviously removes those particles and I highly recommend for everyone wanting clean air in their homes.

Really helps with cat litter dust. It’s run pretty much 24/7 since I bought it over a year ago. I definitely breathe and sleep better, not that I had issues before, but it’s enhanced.

This air purifier is the best money I ever spent. I’ve never slept better. The noise level is low and gives off just enough white noise to help you sleep. The air quality in our bedroom has improved greatly. I don’t wake up with a headache any longer.

If you are thinking of getting the Alen FLEX air purifier to help with allergies or asthma or pets, read on (because I have all 3):
For context, I had been having worsening asthma and allergy attacks over the past few months, to the point where my asthma went from being predominantly exercise or allergy induced to recurring several times a day. After a trip to an asthma and allergy specialist and receiving a full allergy test, I was told that I was allergic to almost everything (every tree, grass and weed, dust mites, cockroaches, cats, dogs, etc. plus other food and miscellaneous allergies). I already knew I was allergic to all of those things but the doctor confirmed that I was on the “severe” end of the scale and I was advised to get rid of our cats and get an air purifier.
As most cat owners know, getting rid of a beloved cat would be like throwing your child out on to the street, so the cats had to stay even if it meant using inhalers twice a day, popping allergy medication daily and maybe just banning the cats from the bed and wardrobe. But we knew we would need a GREAT air purifier to help with all the allergens coming from our furry friends and everything else permeating our allergen-laden Northeast American air. You know how some people have “spring allergies”? I have spring, summer and fall allergies thanks to the wide range of trees, grass, and weeds that all decide to pollinate at different times.
I had been obsessed with getting a Molekule for a while, and if not, a Dyson. But to be entirely honest, neither was in our current budget due to a recent influx of life expenses. My husband and I agreed that getting a second air purifier from one of those brands might be in the cards when we move into a bigger home in a year, but for now, I should buy the best possible air purifier in the $300 range to cover 700-800 square feet.
After days of research and reading hundreds of reviews, I finally settled on this Alan FLEX purifier in Oak.
It’s a beautiful air purifier, and if you have a home with a more natural aesthetic like we do, the “wood” front helps the machine blend in more with its surroundings instead of sticking out like a sore thumb. We tend to like wood, natural fibers, ceramics, etc. for our decor, and I wanted a purifier that was barely noticeable at a glance because it somewhat camouflaged with its surroundings. Because it has such a minimalist design with clean lines and few obvious vents or mechanical-looking parts, I feel it would blend well with most decor schemes, and it’s so great that this model also has numerous colors and wood types to choose from.
As for how well it works, I could not confirm its effect on my health immediately but 3 weeks later, I absolutely noticed a reduction in the frequency of my asthma attacks. While I was having several attacks a day, I now have one every 2 to 3 days, and my health in general is improving with each passing week. With cats in the house, things are never going to be 100 percent perfect in that department but this air purifier has made significant improvements. I also wake up a lot less with puffy red eyes or a scratchy throat.
For the price point – neither cheap nor extremely expensive, I honestly do feel that Alen FLEX may be the best (if not, one of the best) options on the market, and is a wonderful combination of effectiveness and good design.
On the downside? It can be a bit loud when on the highest setting, which may be an issue for those interested in placing it in the bedroom like we do. Not overly loud but it depends on your personal opinion/perception of what constitutes “loud” for such a machine. Personally, I don’t really notice the noise anymore – it’s almost like white noise in the background. And I think that if it’s bothersome at night, you can put it on the low setting, which significantly reduces the noise when you sleep.
Works great ! my Chinese neighbors under me were cooking fish again the smell went right away plus it’s easy to carry around the house , and at night I put it on high speed for a soft background noise to sleep too

Great air purifier but no instructio
I needed a great house filter to get rid of kitty litter box smell. I have been using it set on high for about a month, and it apears to be doing the trick.
Large unit. But very quiet. Sheltering with covid , inside too much and is also cleaning all the air and removing stuffiness.
BUT — where are the instructions on installing the filter???? Do not know if the black sheet with filter. On or off unit? 8 took it off. Still works great .
After running initially on turbo for an hour than a week on low setting 24/7 the prefilter pictured here shows how much dust and pet dander was collected. Usually dust/vaccuum our home every 2 days but no dust after a week. So easy to vacuum the prefilter so your filter lasts longer. Barely audible on low. Simple to use. Glad I did the research and landed on Alen-best in class. Get your money’s worth!

Just wish it ran 24/7. Every 12 hrs I have too turn it back on. I keep it on level 2 (it has 4) due to sound.

Extremely attractive in that it is plain and flat against wall. 5 speed levels are all quiet . Would buy again for sure. Very happy

This air purifier is pretty quiet and easy to operate. I ordered an extra filter at the same time so I do not have to worry about it when the filter is out.
What is very disappointing is when I tried to register the product for the warranty using the card the supplier provided, it asked me to provide a credit card for auto ordering filters. It did not give any option to register the product without providing a credit card. This is terrible customer service and a lousy marketing trick. I suggest suppliers change this approach and let customers choose to buy from there based on the quality of the product, service, and value.
Love this thing – it is so much quieter than the other four brands of air filters that we have in our home. Works really well. Looks great too.
i could def tell a difference in our air quality after I figured out I didn't open the cover and take the plastic and coverings protecting the filter....would totally recommend.

It is worth the investment. Minimal noise, yet it cover more than half of my apartment. I’m thinking of getting another one for the other half of my apartme

I really like this air purifier. It has a sharp, clean look. It is quiet and I really have noticed less dust in the living area where it lives now.

This is between a 4 and 5 star product for me. This is the sixth Alen I have bought since October. I gave my mother this one for Christmas. Amazon had a deal on an open box with a smoke filter and it was too good to pass up. The Flex uses the same filters as the 45i including the heavy smoke filter with over 2 lbs of active carbon. My air is already almost always clear of PM 2.5 with as many filters as I have in my house. What was a little high was HCHO and TVOC. Most people would want these filters for wildfire smoke, for me cooking odors and chemical reduction is a priority. Most people shopping for this purifier are comparing it to the 45i. Their is about a $100 difference between them. For that the 45i gets wifi, auto mode, an ionizer, and a little more CADR. Ionizers are a hotly debated topic on here and I only use mine before I vacuum to collect a little more dust. I do love the Flex and my mother does not need to have her purifier on the internet. So my best advice to you is to buy either one if it comes on sale in your color. The 75i is a true workhorse, but even on sale is much more expensive.
This product works very well on getting rid off smoke smell. We bought this for my daughter because the tenant below her floor is a heavy smoker. The smoke came in from the front door and triggered her asthma and it got worsen. She has been using this product for almost two months and she felt much better. She does not complain the smoke smell in her apartment anymore. I will give it 5-stars.

I bought this for my daughter to use in her classroom, during Covid. So relieved to have something like this for her.

Great air purifier!
I WATCH it pull dust clouds out of the air.
High quality, works AMAZINGLY
I have five different air purifiers in my house, one in every major room. I tend to buy ones that have at least 4.3 stars and only when they are on sale. I’m going to compare this air purifier to the Blueair Blue Pure 121 since it was the last one I had in my 600 square foot living room. They both move a lot of air but the Alen tends to be a bit quieter at each speed. Perfectly timed for this review, my dog is due for a bath (happening tomorrow!) so I can confirm that both the Alen and the Blueair clear the room of pet odors. When I turned the Blueair off for a bit before installing the Alen, the room began to smell like the dog a bit. It was especially noticeable when leaving the room for a bit and coming back in. I was mortified, but thankfully thanks to Covid, nobody from outside the home would have smelled it. 🙂
The Alen quickly cleared the room of the smell on medium speed. It is relatively quiet at that speed, quiet enough to not have to increase the volume on the TV. I noticed that it was doing such a good job, that it was even sucking in some propane smell from my propane heater stove at anything higher than medium. So I leave it at medium since the volume level and performance are perfect for my room.
You can get a lifetime warranty on the Alen if you register it on their website and sign up for recurring delivery of one of their air filters. I opted to do so, especially since the air filters were the same price on the website as they were on Amazon. There are four air filters to choose from (see This listing on Amazon for the four options). They currently range in price from $69 to $119 depending on your needs. They are a bit expensive but if they work and only require replacement every 12 months, I guess they are worth it, right? I’d love to be able to test how each performs but I am going to stick with the one that works best for me without going overboard and that may be the second level one since there are no smokers in the house.
I am happy with the Alen so far. If anything changes, I will update my review. In the meantime, it is still going strong.
I suffer from allergies and could feel the difference in my home using this right away. I am also very impressed with the length of the time the filters last. Well worth the investment if you want to breathe clean fresh air!
This machine is amazing. I have had what I thought was a sinus infection and I received my Allen room air filter two weeks ago and I no longer have a stuffy and drippy nose. I had a dust allergy. It’s amazing how that machine has cleared my bedroom of the dust. I’ve definitely noticed hardly any dust on the furniture . I highly recommend this room air filter..
This product has really performed as advertised. I need clean air and I am completely satisfied with this product.

From the outer design to the inner design to the functionality design this thing is very impressive. Very well thought out down to even minor details that make a difference. This is easily the Air Purifier that Apple would make. Without the Apple price tag.
This air purifier is a real gem. The filter is easily changed and lasts for months. It is very quiet and we noticed major difference in air quality in minutes. I highly recommend. We bought this one for upstairs where are bedrooms are. We are going to get a second one for downstairs. You won’t be disappointed with this fine Air Purifier.
I just ordered this air purifier as we have 4 pets and lots of allergens in this house. The package arrived here in rough shape but the air purifier itself looked great! Still early on, but I am impressed how much cleaner the air feels now since I have plugged it in. Stay posted! I will give an update on a week. So far, so good!
My husband bought two of these, one for the living room and one for our upstairs bedroom which is quite large. The finish goes well with our living room decor. We did notice a decrease in tiny feathers from our pillows, cat hair and dust in our bedroom. Our baby is sleeping with us and she was getting stuffy nose from all the dust. She seems to be doing better. It’s pretty quiet on the lowest setting and at its loudest sounds like a white noise machine. Overall we are still liking this air purifier.
