Air Purifiers for Large Rooms, Cleans 3,048 Sqft In One Hour, HEPASilent Smart Air Cleaner For Home, Pets, Allergies, Virus, Dust, Mold, Smoke - Blue Pure 211i Max

I’ve been using the BLUEAIR Air Purifier for Large Rooms for a few weeks now, and it’s been a total game-changer for my home environment. From the moment I turned it on, I noticed a real difference in air quality — the air feels fresher, cleaner, and there’s a noticeable reduction in dust and odors. Our daughter has very sensitive allergies and after we got this in her room (we have 2), her sleep quality improved. Here’s what I love about it: Powerful for big spaces — This unit handles my large living room and adjoining areas with ease. It doesn’t struggle or make you worry about placement — it circulates air efficiently throughout the space. It takes up about a 2X2X3 space. Excellent filtration — Whether it’s pet dander, cooking smells, pollen, or everyday dust, this purifier tackles it all. My allergies have been much less noticeable since I started using it. Quiet and unobtrusive — Even on higher settings, it runs quietly. You can easily keep it on while you’re watching TV, working, or sleeping without distraction. Sleek and simple design — Easy to set up right out of the box, and controls are intuitive. The unit looks modern without sticking out like an eyesore. It actually looks like an upgraded piece of furniture. Overall, this Blueair purifier delivers on performance and reliability. If you want cleaner air in a large room without a lot of noise or fuss, this is an excellent choice. Highly recommend!

...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.

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.

This review is for the BLUEAIR 211i Max (large room, 3048 sq ft) Primary reason for the purchase...dust. A film of dust always seems to end up everywhere, mostly because of vacuuming area rugs, lint from blankets in the room, and a wood pellet furnace in the basement that heats the whole house during the Winter. The 211i boasts 4 layers of filtration, HEPA/AHAM certified, and can filter up to 3200 sq ft worth of air within an hour. My home is approximately 2500 sq ft, 2-story. I would say the filter makes a noticeable difference especially on the first floor. Less dust settling on surfaces, and it deodorizes the air fairly rapidly when cooking. No one smokes inside the home, but in order to test the sensors, my wife lit up a cigarette briefly from another room, then headed outdoors, so only a trace amount of smoke would permeate the air from a distant room. Within a minute or two, the PM2.5/PM1/PM10 readings shot up from 0 to over 50 (which is polluted air), and the fan could be heard ramping up inside the unit. That proved the sensors were responsive and quite sensitive. About 35-45 minutes later, the readings returned back to 1, then to 0, demonstrating that the unit circulates and filters the air inside the home rather quickly. When cooking, the sensors also go on the uptick and the fan ramps up. Despite what the other reviewers have posted about the sensors, they seem to work surprisingly well. As for noise, on Auto mode, the fan speeds generally stay below 3, and the unit is practically inaudible. Turning the fan up to its max speed, 4, the fan can be heard but even when standing next to the unit, the dB noise level is barely over 50dB, which is about the noise level of an office or library. I've attached a screenshot of the dB measurement, with my phone placed directly next to the unit during measuring for 15 seconds. This is within the advertised specs of 23-53dB. Note that other background noise within the room added to the dB reading, as the room has a humidifier running constantly within it as well. The 211i Max is about the size of a small trash can, so it can be placed just about anywhere. I'd recommend keeping it at least a couple ft away from walls, otherwise the 360° filtration will be somewhat reduced when it's against a wall. The more open the air space, the more effectively the unit will circulate air. When initially taking the 211i Max out of the box and setting it up for the first time, I would recommend running the fan on high (4) for several hours to get a total air cleaning, then flip it to Auto mode and it'll make fan speed adjustments on its own based on air quality. I had zero problems getting the 211i Max onto my Wifi network and going through setup using the Blueair app. The readings generally take a few seconds to show up on screen whenever the app is launched, but the app is very easy to understand and use. Within minutes of connecting to Wifi, the 211i Max updated its firmware and rebooted. Overall the Blueair 211i Max is perfect for a medium to large room, or an entire floor of a 2000-2500 sq ft house. It's very quiet on Auto mode, and the sensors seem highly sensitive to pollutants in the air. Cooking, even trace levels of smoke result in a quick change in PM readings. Highly recommend for allergy sufferers or those who want clean air inside their homes. Docked a star for expensive filters, though they only need to be replaced once a year.

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.

This unit looks nice but it definitely has flaws. Calling an air cleaner "HEPASilent" it should probably be more quiet than it is. The fan is fairly reasonable until you use it at speeds that are actually useful (50%+). The fan in my unit also makes a particular rubbing/humming sound that is likely not normal (hopefully). For an air purifier to be effective, it needs to exchange all the air in a space completely almost 5x per hour, not just once. In many cases, that would require this unit to be operating on full speed, which is loud. The ability for the filter to eliminate odors is also extremely limited. For odors to be properly captured/eliminated, you need literal pounds of activated carbon to capture and hold it. This thin layer of carbon material around the filter likely only has a few grams of it. It cannot effectively trap or capture legitimate amounts of odors/volatile organic compounds. The particle sensor is also unfortunately questionable regarding reliability/accuracy. It consistently shows that interior particle counts are 0 PPM for particles of all sizes. That is very, very unlikely considering the rate of air exchange with outdoor air and the average fan speed the filter is set at. I have compared other particle readers with this one and there's always a significant difference for readings under 100 PPM in particular (The blue air just always reads 0 PPM, despite it actually being 20-75 PPM on the other reader). Lastly, the filter itself is not a genuine HEPA filter. They use marketing terms like "TrueHEPA" and "HEPASilent" as to not technically false advertise. I have compared this filter to lab-grade real HEPA filters and they are not the same. When it does come time to replace your not-so-HEPA filter, you'll also find that it costs about $100 with tax... A steep price for routine maintenance. Considering I paid almost $500 for this, I would consider this very over priced for the value offered.

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.

I would definitely not buy this product again! The first time I set it up, it showed maximum air pollution -- 999 -- and I had to call service to find out how to get the display working. It turned out that its air sensors were dusty. That time a little dusting -- with a vacuum cleaner -- did the trick. But eventually, I had to buy a new filter. Super expensive -- almost $100 if you buy from the company, and stock is irregular. Once the new filter was installed, however, the same problem occurred, dirty sensors, and this time vacuuming the sensors did not work. I phoned the company, and their agent suggested I run the machine in a small enclosed space like a closet for 24 hours. I've just got that started, but I'm not optimistic, and the machine is past warrantee.
