Blueair Blue 3210 Air Purifier for Home, Bedrooms | Ultra Quiet HEPASilent™ Technology | Removes Pollen, Dust, Allergens, Mould, Bacteria, Viruses, Pet Dander, Odour, Smoke | 3 speeds and auto mode

The media could not be loaded. I’ve never owned an air purifier before, but after reading that they could help alleviate night-time wheezes and sneezes, I figured I’d give it a go.I’m very impressed. Almost immediately the air felt cleaner. As I use it in my bedroom, I wanted a unit that was quiet, and I’m sure they don’t come quieter than this. There’s a night time function which I can’t even hear whilst stood right next to the unit. Fan 1 is slightly louder, and same with Fan 2, slightly louder again. Fan speed 3 is loud, around 48db, but unless you purposefully select it, or have it on Auto-mode in a particularly “polluted” environment, then you’ll never even notice it’s on.The Air Quality Indicator is a great addition, and works really well. I thought I might have had a faulty unit, as the AQI was constantly red, even when using Fan 3. I set it to Fan 2 and went to sleep. Turns out it was detecting vape particulates in the air, because after waking up, the AQI was blue (indicating good air quality); the unit had cleaned the air whilst I was asleep and obviously hadn’t been vaping. As soon as I breathed out a couple of lung fulls of vape, the AQI was red. Now I know how it works properly, I’ll have it on Auto during the day if I’m in my room. It might sound silly but that AQI is a great behavioural nudge, allowing me to be more mindful about how often I pick up the vape and have a blast.For £99, it’s certainly not the cheapest air purifier on here, but I’m glad I bought this one. The design is minimalist and unobtrusive; and with a power draw of between 2-10watts depending on your settings, you can leave it run continuously for pennies.

This is my 1st air purifier, I really like it, its easy to use and quiet. Most importantly you can feel a difference in air quality, and the air sensor is excellent.

I find this a useful machine but with limitations. These are as follows. In a bedroom in which one half is obstructed by a double bed the machine may not be effective for the area beyond it. Using two in the same room may not be advised. You may notice in the demonstration video the floor has no carpet. There is more dust in a room with carpets, beds, pillows, cushions and couches and fabric backed chairs. I did not find this machine picked up and illiminated dust on any speed. This still settled on surfaces. But, I did find when visited by people with colds I did not catch them so it may well work on these. It certainly clears the air if you over heat a mince pie in your microwave for example but, not in 30 minutes. Took a bit longer than that but it did. Conclusion. A small, inobrusive and reasonably quiet HEPA air filter but with reservations. All air purifiers sold in the UK should comply with safety air processing standards.

Excellent air purifier, picks up stuff from the other side of the room so great sensor and air feels lighter/cleaner. The nightmode is completely silent and dims any lights so it doesn't disturb you. I would be lost without this, 100% recommend it for a fraction of the cost of a Dyson! Same results though!

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 really wished this air purifier would be the answer to my dust allergy...but sadly, as a light sleeper, it couldn't stay. The slight swoosh of air movement on night mode wasn't too bad, but the intermittent rattling of the fan wasn't something I could sleep through, so it had to go! I guess I might've been unlucky and got an faulty rattling one, but even so, you'd expect a quality fan would be near silent on a slow speed. I would still recommend for daytime use as its a nicely designed thing, but not if you need it to be super quiet at night.I ended up with a Philips 2000i which is much chunkier, more pricey and not as pretty...but its on another level in terms of how fast it cleans a room and is silent on night mode. Happy days (and nights!)

Air cleaner, smells better and virtually silent. Big but needs to be that size for the throughput and noise.

I like it very much because it works! No longer sneezing and using lots of tissues in the morning. However, when you have a fan on overnight, because of the hot weather, it seems to interfere with the overall air quality somehow.My only criticism is that the controls are not great - you have to press x amount of times up to five for various settings. I do that but don’t always find my taps register and I don’t get the required setting. You do get there in the end but it seems a rather low tech way of controlling the unit. However, it has made such a difference to start the day without snuffling as if you have a cold that I very quickly wouldn’t be without it.
