    Stopped working within weeks. Unable to return. Started making a terrible noise and unable to turn off without unplugging. Used to be a reliable brand name but on investigation being used under license. DO NOT BUY.

    In the winter I have to dry my washing in my spare bedroom which results in condensation and some black mould. Since I bought this small dehumidifier the situation has vastly improved and everything has dried far more quickly. It seems to be very economical on electricity too which is a real bonus.

    First of all I dislike the blue light as it’s used in the bedroom where I like total darkness. Otherwise it collects plenty of water and the filter helped my sinuses greatly. I do switch it off at night as it’s not the quietest but, still helps me and don’t have half as much condensation on the windows in winter!

    There are a lot of reviews of small dehumidifiers stating that they struggle to remove moisture from spaces. I’m happy to say that my flat is significantly less damp since purchasing this. Also, my clothes actually air dry fully, now.

    Our boiler was replaced and its heating output via radiators is phenomenal. We used one room to dry cloths because of the recent cold weather. So moisture has to uo somewhere.

    We put this on and I was astonished how much moisture there actually was in the room. It does exactly what it says it does. The ro felt dryer and the air quality did also feel better.

    Don’t be put off by the 1l container. This product is superb.

    Excellent! This takes so much moisture out of the atmosphere in a room we are going to get another for the bedroom. No more condensation so it is very good for our heath.

    Im always impressed at how much water it pulls out of the air when the room doesn’t even seem damp
    A must have if you’re being more mindful with heating during this energy crisis

    Golden Review Award: 2 From Our UsersHas made a significant difference to the bedroom. I was cautious because of the reviews. The plunge into buying it was worth it. Good for a small bedroom. Can sleep with it in low. The only thing I’d like to be able to do is turn off the blue led. There probably is a way I just didn’t read the instructions. Managed to do so

    Golden Review Award: 5 From Our UsersWe got this for the babys room as we have a damp house. This is perfect for a small room with bad damp or any sized room with slight damp issues. Its not too strong so doesn’t dry out the room. It takes around 4 days for ours to fill up which I think is fine considering its small and we have a lot of damp. Its easy to empty and small enough to sit on his chest of drawers and looks pretty stylish. Overall I love it and will buy again in future.

    The design is sleek and modern. It functions well as a dehumidifier and air purifier. There are 3 fan settings and settings to use it as a dehumidifier or just as an air purifier. The only problem is that it’s rather loud when on the highest fan setting of the dehumidifier.

    I have asthma and have been having some real problems this winter. I’ve had air purifiers before but hadn’t had one in the past few years. I decided, after hours of research and looking on different shops and sites, to just go for it and went with this one.
    I have found that the air quality in my bedroom definitely improved from the start. It seemed fresher and my breathing was better. The dehumidifier hasn’t been used as much yet but it does work. I’ve placed it on my windowsill and it helps with any damp there and collects the water. Very easy to empty.
    It is so simple to use. I do find that it is kind of noisy? But nothing that I can’t ignore after a minute. I do turn if off at times if it’s bothersome but it’s not enough to detract from how well it works.
    *I will update if I remember when the summer comes. I struggle with humidity so that will be the real test for me. So far so good though.

    This is a life saver. It has eliminated condensation and mold. I bought this because I started getting sick which I suspected was due to mold. 5 days later and I am better. The noise is the same as having a fan on but there are blue lights. It doesn’t affect my sleep. I can be a bit funny with getting to sleep when it comes to noise and light. I would definitely recommend this and would definitely buy anothe

    I bought this product for my girlfriend as she has been having problems with dust mite allergies. My room is usually very humid, but after turning this product on her allergies completely faded after a few hours of it going. I sleep with it no problem on the low setting, as the higher ones are much louder, but it does everything it needs to and it can be carried in between rooms if needed without much work due to its light weight.

    It has been running for the last two days and has greatly reduced the dampness in the kitchen and even the rest of the house, which I wasn’t expecting. It is a bit loud, but I think for the price, it’s of great value. I would highly recommend it.

    The third dehumidifier that I own. It’s probably the most attractive but not the most efficient. That said, my other two are bigger and consume more electricity so it’s really going to depend on room size and the dampness. You really need to close the window to appreciate the full effect, otherwise you’ll be just sucking the water out of all the air coming in through the window. What does favour this one though is the added air purification. I’d recommend this for a smaller room such as a bedroom. I actually use my other ones for my laundry room but this is smart enough to take a place anywhere in the house. A nice option that looks good and modern.

  22. Melissa Jones says:

    Golden Review Award: 2 From Our UsersThis is a neat little air purifier and dehumidifier and I would recommend this to anyone looking for an item of this sort, especially those with breathing issues and could benefit with an air purifier.
    The unit is relatively small and easily manoeuvrable, but this also means a smaller tank capacity for the dehumidifier to hold the water. It’s just a trade-off, and one I’m happy to make. Just need to empty the water more often, but at least the unit is compact and out of the way when not needed.
    When the tank is full, there’s a light that shows it and the water pushes up a trigger to stop the unit, which is good for safety measures, although this is pretty standard. Dehumidifiers have come a long way and this is definitely an improvement over the first unit I used, which was a lot bigger.

    Not exactly perfect and there are a few kicks to this.
    The first is the noise. Low is quiet, but not silent. High is just loud, very loud. Also, pressing the buttons is very loud too because it beeps. I could really do without the beeping sound when the buttons are pushed, because it will and it did wake other people up in the house in other rooms, and needless to say, if you share a room, it will definitely wake them up, since operation is more than a single button press. Even turning the unit off takes more than one press on the power button, so when you want to change the settings, from high to low for example, in the middle of the night, it’s not ideal.
    Can be used as just an air purifier, but can’t be used as just a dehumidifier. Somewhat of a downfall, because it would be nice if both can be operated independently. Not a major issue, but nonetheless should be noted.
    Emptying the water tank isn’t the easiest. Pulling it out is easy, but the water tank is designed in a very strange way. There’s a lid with a hole in and the lid fits on weirdly, so it spills easy. Take care when tipping out the water and make sure to do it over a sink or drain.
    The yellow warning sticker about getting all the contents out before first use is awful to peel off. This sticker is only necessary for a brand new unit that’s never been used, and they could easily use one of those easy peel stickers to alert customers, but no, they choose the worst kind of sticker possible. I tried peeling it off and the top layer instantly tears, leaving the bottom paper layer glued on. Absolutely horrible sticker, so I’ve just left it on, but this taints the stylish unit as there is just an awful sticker stuck to the side of it.
    Final complaint is I don’t know where to get replacement filters when this one’s done. I’ve tried looking, but without an exact model number for the filters, it’s not the easiest to get replacements for.

    89.99 isn’t a bad price for one of these units, and it’s definitely recommendable.

    My son has severe eczema, which is not related to any food but it is from dust, dust mite etc. I used this device and I can feel the freshness in his room. Moreover I have noticed his less itching in the night, so definitely it is working.
    My only criticism is, its a little too noisy for children room, he can’t sleep with that sound. So I run it for 2 hours before his bed time, still works out well for us.

    Overall this humidifier works in a similar way to most others I’ve tried – as I live with a COPD sufferer we personally love knowing the air is clean as it helps prevent irritation. Aside from the air purification this unit also works as a humidifier, which was the main draw for me as our house does suffer damp especially during the winter months. Having had this on for the past couple of weeks it does seem to reduce the amount of moisture in the air and so with even longer use I can see this being very beneficial in preventing damp spots/mould.

    The only real downsides for me honestly were that it isn’t the quietest unit I’ve used, I can sleep with it on but I don’t mind white noise as it tends to help me sleep, very light sleepers may find it a bit too loud. And I think they missed a trick by not having a dehumidifying option as a stand-alone, I don’t mind so much as we really always unitise the air purification but think this could’ve been a great option.

    Overall a sleek device in a much more compact design than a couple of others I’ve owned, it works very well and the price is great in my opinion.

    Update: after less than a week, the dampness on the wall has disappeared. Very impressive results

    This is a compact dehumidifier & air purifier in one. Most on the market are quite bulky & take a lot of energy (expensive to run) & thus not energy efficient. Although I haven’t been able to compare energy usage, due to size , should be less.
    I’m really impressed by its lightweight & portable design. The one I have us very heavy, about the size of a small side table & not easy to move from room to room.

    For a start, it’s by a well known brand. In half a day, I got half a litre of water & I’m really impressed. I have to see over time how we it performs. However, I could really feel the difference in air quality. Air was fresher & cleaner.

    It also has an H13 HEPA filter to remove 99.95% of unwanted air particles, so you can breathe easy.

    Thus is an ideal candidate for asthma sufferers & those with breathing difficulty.

    Good value for money & very useful for UK homes as we have a lot of humidity.

    I really love how i can feel the air circulating around the room with this on, i also have definitely noticed an improvement in air quality. It makes the air feel fresher like that of taking a countryside walk.

    This machines primary function is as an air purifier since this option is required to be on and can’t be turned off to use the de-humidifier solo. But normal de-humidifiers draw in air anyways, so why not have it purified in the process? This is a great machine.

    This machine is pretty robust if you happen to accidentally knock it. The water container is made in such a way that water won’t go everywhere if knocked over. It’s easy to slide out and empty too.

    The dehumidifier does work at taking moisture from the air which is great. Less moisture equals less black mold ect. It does work very well but can’t compete with larger bigger capacity de-humidifiers however not everyone has such high humidity indoors as to warrant the use of a large capacity de-humidifier and in such cases one of these is ideal. I think the best way to look at this machine is as an air purifier with additional benefits.

    This machine definitely makes a big difference to air quality. It is only close to silent on the lowest setting. But i like it on medium or high to really feel the air circulating around the room. I am a lover of white noise though and have often found white noise to help me and my partner drift off on a night. But if you don’t like white noise you may not like this on medium or high as it does make some noise.

    Overall i am pleasantly surprised with how well this performs. This is a good quality product from Russell Hobbs.

    I was really excited to receive & test this dehumidifier & more so from a trusted brand Russell Hobbs. This is an ideal size for a small home & not too bulky for what it can actually do. Everything is in an easy-to-reach place — the filter & water tank as shown in the photos.
    It is a 2 in 1 dehumidifier/Air Purifier which captures Bacteria, smoke, pet dander, pollen, dust & viruses. It reduces humidity & helps the spread of existing damage caused by damp & condensation in the room.
    My daughter’s bedroom has been affected by dampness & mold which we started noticing getting worse for the past couple of months. A section in the corner of the ceiling is where the worst part is so this was going straight into her room.
    After using it for a couple of weeks now, we have really noticed a difference. In addition to this problem, my daughter has asthma, so this just doubles up to help with her asthma & breathing as well. I also use it during the day in the downstairs utility room to help with the condensation from the dryer.
    It offers so many benefits I couldn’t be happier to have one.

    The water tank is at the bottom and holds up to 750ml of water — easy to remove & replace. It has an auto cut off function when the tank is full. The touch control function and speed/3 speed option buttons are on the top & easy to operate & include easy to read instruction manual.
    It is lightweight but I would say that on the highest speed it is really loud but for what it is doing & my daughter said she hardly hears it at night so this is not really an issue. I really am so happy with this product & would be confident to recommend it.

    Love This Produc

    Golden Review Award: 4 From Our UsersI didn’t think I had so much moisture in my house.
    I put this in a little bedroom that I didn’t consider to be damp just to try it out while I got used to the fan noise, I only had it on low.
    The next day I decided to see if it had collected any water, I expected maybe a little puddle in the bottom. I was astonished to find 200 ml in there and this is from a relatively dry room. Wow.
    So I can positively say that the dehumidifier works very well. The next day I put it in our bedroom. I emptied the water collector again. This time I got 550 ml, that’s amazing. I have had a cheap dehumidifier before which took weeks to get less than that amount of water, I passed that one on to a friend as it wasn’t very good.
    This also helps with pollen, dust and cigarette smoke so if you have allergies or someone in the house smokes then this is for you
    The price is competitive for this type of product.
    .
    Things you need to know.
    The filter is easy to install but you will need to take it out, unwrap it and put it back before use.
    Easy to empty the water collector.
    You can have it on either dehumidifier and air purifier or just air purifier, you can’t have it on just dehumidifier and it has low, medium and high settings.
    You can have it with a blue light or you can switch the blue light off if you have it on air purifier. There doesn’t seem to be a facility to have it without the blue light when the dehumidifier is on.
    You can hear the fan, I’ll keep it on low until I’m used to it.

    This is such a fantastic 2 in 1 Dehumidifier that is not only compact but also lightweight making it easy to transport around the house.

    The Fresh Air Pro has an auto cut-off function when the tank is full, so it can operate without needing to be monitored.

    There are 3 speeds which can be used however I have found I don’t really need to go above 1 most times.
    I sometimes find it hard to sleep and this has really been helping.

    I absolutely love it and have noticed huge differences.

    Would 100% recommend and feel this should be in every household

    I’m I live with this machine! Omg it’s amazing… where has it been all my life haha. First off the machine is Russell Hobbs branded, so you know the quality is already there. Arrived in a nice sturdy box with simple instructions to follow. Unboxed the item is roughly the same size of 4 x 2L bottles of pop places in a square, so fairly large but no but it’s got to be for processing the air! Now onto the purifying aspect, there is 3 levels from quiet mode which still produced a sound, but best if you’re sleeping, then setting 2/3 which processes the air quicker but has got a noticeable sound to it! There is also a build in blue led light which is cool if you like a nightlight (if planning to use a night) but can also be turned off. Built into the machine is also a dehumidifier with a 1l tank. You can run both together or one at a time. I had mine on for 24 hours and it actually collected half a tank full of water! I was so amazed as I didn’t realise the room was slightly damp. Overall I’m not to bothered about that part but I’m loving the purifier. Within literally 12 hours of use it cleans the air and you can notice it smells instantly fresher! Especially in a slightly muggy room with the windows not being opened due to winter! I honestly love it so much. I’m getting one for the living room haha.

    This Russell Hobbs combo dehumidifier/air purifier is surprisingly smaller than I expected, in fact it’s a stylish little addition to home without looking like an eyesore! It filters and dehumidifies the air around your home so you can be sure you’re breathing in cleaner air, perfect if you have allergies or such! It’s surprising how much moisture it actually catches around my home, the water tray soon fills up with water I had no idea how humid my home actually was!! It automatically cuts off when the tray is full to avoid being overfilled.

    It will also be perfect for anyone suffering with damp or condensation in their home, it quickly draws the moisture out of the rooms and helps maintain humidity levels whilst purifying the air. It’s quite a quiet fan but I wouldn’t say it’s silent, if you plan on using it in your bedroom I would recommend the lowest setting, any higher is probably too noisy for sleeping.

    I hope you’ve found my review helpful! 🙂

    This is a great little compact dehumidifier.. It is compact enough for a small room and light enough to transport between rooms if need be. It comes with clear instructions on how to operate it, where the filter is and when to empty the water tank. There is a low level hum from it but overall is quiet. It is a good product and even after only an hour’s use you can feel the air is cleaner and fresher. It is a little expensive for the size but I definitely think in the long run it will be worth the money to breathe easier and keep damp at bay.

    Golden Review Award: 5 From Our UsersGreat product nice looking and on low isn’t to loud I keep it on over night and I’m able to sleep.
    Any higher would definitely be too noisy.

    I would of given 5 stars but it doesn’t allow the option to just be a dehumidifier.
    It’s isn’t a big deal though because both work well together but it would of been nice to have that option as I brought it to use as a dehumidifier. Saying that the air purifier will be great for my hayfever in the summer so it’s good that the dehumidifier can be turned off.

    Easy to use and the light is a nice touch especially at night so it’s good you are able to turn it off during the day.

    I brought this mainly for the dehumidifier, but it’s actually more of an air purifier and you can’t turn that off – you can only decide whether you want to use the dehumidifier option as well.

    However, it’s a really nice, modern looking product and suits really well within my bedroom, the noise isn’t too bad, i have it on low and it sounds just like a fan although on medium and high it can get quite noisy.

    The led lights are a really nice touch and i think you could go a couple of days with the dehumidifier on without having to empty it as i’ve had it on 24 hours now and it’s around 1/3 way full.

    Golden Review Award: 4 From Our UsersI was looking for a dehumidifier with air purifier function and this was the only one I could find on Amazon at an affordable price. I’m very happy of my choice: it arrived earlier than expected it looks very nice and does a very good job for all its functions. It has three fan settings (low, medium and high) and I can select whether I want the dehumidifier only, the air purifier only, or both functions together. This means it can be used also in the summer only as a purifier. It also looks very elegant. It’s a bit noisy but I don’t mind it.
