Excellent for everyone's health. Especially people with allergies. I turned it on and a day later my itchy dry & sometimes wet, eyes stopped itching. For that alone it's worth every penny. My place is completely carpeted. Removes dust particles in the air. On automatic, very quiet, not noticeable. When manual, set high, there is some noise, but not bad. Removes smells. Indicator on front gives you a blue, green, orange or red. Excellent down to poor air quality. Needs to be turned on high. On top of the unit is the controls & the number to indicate what air quality. Mine is for 3,000 sq feet. My condo is 1,200 sq feet, but I have an open loft above the kitchen & dining rooms. I have taken naps with it on & sleep fine. I'm a very light sleeper. No flashing lights. Just one bright dot in front.

It cost about $265 with sales tax but it cleans the air space within your home within an hour. It gives the readouts for the different grades of particles in the air, ultra fine, fine and coarse sizes. It is pretty quiet as well. It is not too heavy so pretty easy to move around but you have to grab it by the bottom. It also can operate from your smartphone using the Blueair app. The filters need to get replaced about every six months or so and they are not cheap. This is not a budget friendly machine, but it gives you the results you need and is easy to use.

...after 10 months of use in a 2100 square foot house. I run it on automatic and the fan speed remains low, while moving air and staying quiet. The performance of this unit is quite remarkable beyond what my HVAC cleans with a MERV 11 filter. This product is especially helpful when noticable odors are evident - as from cooking. The unit almost immediately senses the odors and begins ramping up the fan speed to clean the air. It works rather quickly. Impressive when cooking fish and the associated odors that produces. Still and my first filter. Did order extras and an outside unit sock. Customer service is excellent should you have any questions. Well built and expecting it to last a long time.

So I didn’t think this worked at first. If registered my living room air as perfect. Well about a week later some cheese was spilled in my oven. I registered it and got to work! There wasn’t even any smells left over! I have noticed a difference when I come into the room after being in the other rooms without one so I do plan to purchase more. It’s big but it gets the job done. My living room, dining room, and kitchen are basically one big room and it handles all three. It feels very sturdy. Noise level isn’t bad but it’s not great either. It’s like having a fan on to sleep with but it doesn’t bother me.

Best air purifiers I have ever had in my life- so good that I bought one and then another 3 days later and we are going on 1.5 years with 2 now. I am not a freebie or paid reviewer or whatever and I stand behind the 211 as an awesome product. I told my HVAC guy that I didn't think my airflow was right because my filters were almost new looking and he said everything was fine- you're just clean livin'. Nope. Messy as hell and I have 2 rescue cats. That was hilarious. Dust/dander was almost gone and allergies down big time for sure. OK, negatives: their filters are way too expensive especially if you have multiple unit replacements- for sure look into those costs before you buy. The carbon filter layer is very skimpy and probably a marketing tool; I buy filters with 10x more carbon for my cats' litter box and Blue Air needs an improvement here considering the cost of the filter. The app is ok, but I found it to be unnecessary- don't bother if you are app focused. It's loud on its highest level, but level 3 gives a good white noise. One of the 2 units has a fan hum that it didn't start with and that the other doesn't have, so worried about motor longevity. My overall review is that this is the best product in its class and I highly recommend it.

I have purchased two of these and overall I like them. It was a little challenging to register the product. I first tried on their website which didn't work right but it allowed me on the app that I had downloaded onto my phone. The units work well and are fairly easy to set up. It works through the app as well as from the unit. Mostly I use the console on the unit if I want to change anything. It doesn't look difficult to change the filters. The inside one is a little pricey if you want the more hypoallergenic filter. However filters seen to last around six months. The controls are easy to use. The hardest thing was to adjust the dimming of the light which was a little tricky before I got it. It is not clear whether to run it on the automatic setting or use the fan for faster air exchange. I find the information offered not that detailed. I have taken to running in on the "2 fan blade" setting (low medium?). My only complaint is about running them on the two higher setting. In both one has a mild "buzzing sound that won't go away. And the other has a mild vibration such as fan bladed not being quite balanced. But since it doesn't really seem necessary to run at the higher speeds, it is not a big issue. At the lower setting it is quiet. Being large they are somewhat unwieldy to move around and as such I bought roller caddy's like for large plants which work well. After a couple of months I decided the one that is noisy and buzzing on the higher setting needed to be fixed or replaced so I contacted Blue air support. The site is pretty confusing for support and after going in circles I decided to try chat support. It seemed pretty good but besides the wanting the serial number and purchase receipt they wanted a video of the problem. I pointed out that the audio on the video might not exactly replicate the natural sound in my room. From what I could tell the buzzing (at a higher treble level) on the video was not as noticeable as in real life. Anyway the rep sent me an email to attach the files to and I sent them in anyway. So I never heard back from them. After a week I sent another email to the rep asking about any update and have heard nothing further since. About a week after this last posting I received a response apologizing for the delay. On reviewing my completed documentation, a few days later I was informed that they would be sending me a new unit to replace the "bad" one and a return authorization and label to return it when the new one arrived. The new unit arrived promptly and did not have the problem of the first one. Since I am very pleased with the outcome I have updated my rating to reflect this. Again my only concern was the delay in response to my submission. Given the outcome I feel I should let it slide. I like the machine well and they stood by it.

I don't think I could be more pleased or impressed with an appliance than I am with the Blueair 211i. Living in a 50 year old house that up until a year ago never had the air ducts professionally cleaned equaled a constant battle with dust. Not just dust but enough dog hair to make enough blankets for half of NYC if spun and woven. Having at least two double-coated canines at a time equals ALOT of airborne fur and dander. Researched air purifiers and decided on the Blueair 211i. While the capacity of the 211i is twice the square footage of my home, that was done on purpose. I don't plan on being canine-less anytime in my remaining time on this rock and the larger unit can help "Aussie Proof" the dust levels. Getting to the unit. Whisper quiet under normal running - don't even know it's there. Mine is in the center of the house which is between the kitchen and living rooms. Happen to start creating carbon instead of dinner? The Blueair will automatically sense the additional particulates in the air and quickly remove them. For a fast as the fan runs during one of these episodes it's still pretty quiet. The "prefilter" or outer fabric cover does a great job catching the doghair and dust on it - it's easily cleaned with a vacuum and can be thrown in the washer when needed. With the light blue prefilter on mine, after a couple of days the subtle difference in color is a visual indicator to clean it off. The prefilter takes a bit of the load off the HEPA filter inside. After five months of 24/7 use now, the HEPA filter is still in fairly decent shape. The 211i has a LED indicator on the front to give you a quick visual on the filter condition. Nice feature to have on it. Without the exterior prefilter, I'm sure I'd have had to change out the filter already. Replacing the filter is as easy as giving the top section a quarter turn and lifting the section off. Reach in, swap the filter, put the top back on and set the prefilter in place. I couldn't ask for anything easier to do. I've also noticed that I'm not coughing as much inside the house now - definitely getting the air properly filtered has had a positive health affect. The fact I've not noticed any discernable increase in the electric bill is also a positive! If you're seriously considering a top notch/quality home air filter, give the 211i a hard consideration. I've recommended it to friends and haven't lost one yet after they bought one...!

Purchased this Blueair Hepa air purifier almost a year ago and it has worked very quietly and efficiently, keeping our home air fresh and almost allergen free. (Air will never be totally allergen free due to leaky doors, windows, etc.) Noticeable difference especially with the wildfire smoke that many countries are experiencing. It is interesting to hear it automatically speed up when you are cooking something smokey. I like being able to control it or check in via iPhone. HEPA filter is combined with carbon filter to remove odours. Easy to change filter and relativity inexpensive to replace, also there are many after market filters that are cheaper if you wish to go that route. There is also a cloth pre-filter which you can remove and wash as required to extend the life of the main filter. Lighting on it is also dimmable. Very attractive and highly recommend.

Very effective, works well and easy to use. This purifyer is helping me everyday from nasty allergens from cigarette smoke. I just moved into a building with big smokers and poor ventilation. I knew about my cigarette allergy but I hadn't known how severe it had become. This purifyer is ideal for all kinds of smoke, from cigarettes to forest fire smoke, because it has a carbon filter. I leave it in automatic mode and it filters the air using very little energy to keep the air to "excellent quality". There is a light that changes color to inform us of air quality. When it's blue, I know I can breath easily. You can hook this purifyer to your Wi-fi and use special app to manage it, but it's not necessary. I'm using it without it and it's going very well. It's very quiet compare to my previous one I bought 3 years ago. The filters aren't cheap and it needs to be changed every 6 to 9 months. I haven't had to change it yet, but I'm hoping it lasts as long as possible and that there won't be any problems. I'll edit this review when it's time for a change.

It works well. The price is hight and filter too. I like that it is wifi. I like too that I can control it via smart plug (on/off) and do routine, contrary to my old serie 500/600 that has remote control and it is impossible (Attention: i love my old 500/600 that I have for many years and I am happy with). Hoping the quality has not changed with the time. It is quiet and I like the concept capturing circularly contamination and pushing clean air only vertically on top. All around fabric cover could be easily washing. I am concerned about the set point when it is in automatic mode. In 3 weeks of use, I never saw changing from automatic mode to hight speed clean air. I think the sensor are very bad contrary to serie 500/600 that easily detect smell, contamination and quickly pass from automatic mode to hight speed clean. That could be improved seriously. Finally , I saw purifier increase speed at higher level when the numbers on screen at PM2.5 reached higher that 36. Led light in front of device changes colour: 0-12 blue, 12-22 green, 22-32 yellow, higher than 33 red and speed increase.

Purificateur d'air Blueair. Très efficace ce purificateur d'air non seulement purifie l'air mais aussi la poussière domestique. Je possédais des appareil Dyson depuis des années, je m'en suis départis pour acheter des BLUEAIR Je possèdes 3 appareils de différentes capacité en raison des pièce dans les quelle il sont utilisé. Aucune comparaison avec Dyson, je ne retournerais pas en arrière.

Got this model because it was top rated by Consumer Reviews for a large space. The first one that I got quickly developed a hum and Amazon arranged a free return and sent another without additional cost. I got mine for a great Black Friday price. The second one works great and is nearly silent when fan is on 1. The app works well or it works manually on the device, but I'm not sure if you have to set it up with the app for it to start working in the first place. It is very large. You need somewher for it to live. I'm a little disapointed that it's not helping my always slightly runny nose but really got it for ragweed season so will have to wait til next summer to really assess it's true value.
