I bought this after we had some work done in our flat and the reinforced concrete dust was everywhere, and I didn’t fancy breathing it in. Now I just run it overnight on sleep mode, which I find very quiet and pleasant. It definitely reduces dust (a bit), and makes me feel better having the windows over the High Street open during the day, knowing we can filter at night.

I was sceptic when i was looking for something like that, but from very first day my daughter start feel better, this device collecting all dyst and cleaning air in her room… Happy and highly recommend to everyone.

I have suffered from dust allergies all my life, and the winter season with radiators on always gets me. Since having this for about 2 weeks I have had no sinus troubles at all. Completely gone. It’s really impacted my life. I like the functions, sleep mode is quiet, and it’s stylish and fits well with the room. My air feels fresh and nice to breathe in. I’d recommend this to anyone. I’ve never had one before so don’t know how it compares but am certainly not wishing I bought a different one.

Great range of modes and night mode is quiet. Works well in bedroom and looks good. Shame they can’t get more power in this size though as would be good to have in lounge and technical reviews suggest the active carbon isn’t quite enough over the longer term compared with their squarer 205/405 models. Kept the sinus/ allergy issue at bay though.

After a certain procedure I ended up with a very particular condition that made me physically dependent on nasal sprays to make sure I can breathe. I literally used to wake up at night with all my nasal passages swollen and only after a couple of sprays and a good half hour of wating I would be able to have the pressure in my head releived so I can breathe again and live again! So, I ended up with air purifiers in every room of my house as they seem to be relieving some symptoms. This particular one was put to the test in the bedroom and over the past month I had been keeping a close eye on how it affects my breathing at night.
I cannot say that it magically helped me find my breath back and reclaim my full health, but it most certainly alleviated some symptoms and I can breathe easier at night and do not wake up every 4 hours for another dose! In fact, I sometimes now last until the morning before needing another doze of my meds, so….it is quite telling I would say! It has been running on the auto mode and depending on the activity in the room ( based on how much the air is disturbed, I’d say) it either intensifies or slows down its quiet humming. I am used to it now, so cannot even detect whether it is on straight away without paying particular attention to it, so it is pretty silent and suitable for our bedrooms. It is well priced too, so I can recommend it, as it is on a par with other purifiers I have, some 3-4 times more expensive!

Used for the bedroom, very quiet and certainly improved air quality. Easy to use, several modes including boost. I have it on 24 hours and has shown a definite improvement when sleeping

Great product, bought as my son was arriving for a visit and he suffers from hayfever and is usually effected by the change in air so I thought I’d try an air purifier in my guest bedroom. It worked a treat he has managed quite well, whereas normally he would suffe

Not only does it look smart it works too!
Running happily in our living room for the last few weeks with minimal noise it’s made a noticeable difference to the inside air quality.
Both the allergy and asthma sufferers in the household feel clearer in the same room as the purifier.
The reduced dust levels are particularly noticeable on the television screen. Normally a dust magnet, it’s been clear for ages.

Easy to use central control on the top.

10 out of 10.

So far so good, bought for more daughter who is asthmatic and has a lot of issues in the summer, it seems to be working so far.

Since it’s arrived its been running in the background of our living room and hardly makes a peep, its great for our family who have to deal with their hay fever allergies and asthma.
It’s sleek and minimalist design makes it dead easy to set up, 4 modes activated by a single button in the centre, that shuffle through 1-auto, 2-nighttime,3-everyday, and 4 the highest settings.
There are 4 settings via 1 button in the middle – 1 press is auto, 2 presses is night mode, 3 presses is everyday mode and 4 presses is boost mode (press again to turn off).

It’s also great to keep in the bedroom during the night and has been a massive helper for our sleep.

I don’t write reviews but I bought this, sceptically, to see if it could help with the bizarre amount of dust that sits everywhere in the main bedroom in my new house. I’ve never had this issue before and it is only in this one room. I wasn’t interested in ‘cleaning’ the air in the room, but just dealing with the dust problem. I have had it permanently on low/auto for one week: it is almost silent and there is no dust! It is amazing. The sideboard top, which within 24 hrs of cleaning, is usually laden with a mat of dust, is, after one week since cleaning and one week of the BlueAir 3210 being on, perfectly dust free as are the blinds. This is a fantastic piece of kit and the best purchase I’ve made in a long while.

I own 2 Blueair 411 and bought this one because of it’s Auto function. Don’t bother. The air purifier will only increase it’s fan speed once the PM2.5 in your room has reached 10. I have asthma and don’t want a higher PM2.5 then 1 in my room. I contacted Blueair and they confirmed it. When the air purifier is running on Auto in my tiny bedroom I have a PM2.5 of 4. I use an excellent and accurate air quality monitor to check that. It’s not doing much on the night time setting and auto setting. It’s basically silent. However, the second fan setting is not as loud as the second fan setting of the 411. I am using the second fan setting at night. I do have the 211 in the living room and after having used them for 3 years my asthma is much better. I no longer need the steroid and long acting reliever inhalers.
