BLUEAIR Blue Pure 211i Max Smart Air Purifier for Large Rooms up to 3,235 Sq Ft, HEPASilent Air Cleaner for Pets, Allergies, Smoke & Dust, WiFi Air Purifier with Auto Mode, Quiet Air Purifier for Home

The 2111iMax works great! It removed food odors quickly and pollen from my home when someone had a window open. It is quiet on setting 2 which is what i have it on all the time. I like the light dimming feature, the lights can also be turned off, the touchscreen, sleep and auto mode. I love that it's AHAM Verifide: CADR 450 cfm Pollen, CADR 452 cfm Dust, CADR 435 cfm Tobacco Smoke at 674 sq. ft. The air purifier was packaged well and arrived without damage. Setup was easy but I do wish there was a way to connect the wifi without entering my wifi password such as pairing. The warranty is very good compared to most other companies. One year is included and after you register the Blue Pure Max Series air purifier on the Blueair website, they provide an additional two years. A three year warranty is decent compared to some other companies. I have had other brands of air purifiers that stopped working at the one year mark right after the warranty expired.

Really. - In my case, my allergies are down since I started using this. Hard to know if this is one of the reasons. But, it seems likely. - Quality seems very high. Cons - Have not identified any cons yet. Reliability is TBD, for example. Summary - I would recommend this product!

⭐⭐⭐⭐⭐ **Breathed the Difference Within Hours – Worth Every Penny!** I don't usually take the time to write reviews, but this air purifier absolutely deserves one. The **BLUEAIR Blue Pure 211i Max** has exceeded every expectation. From the moment I plugged it in, it was incredibly easy to set up, and within just a few hours the air in our home felt noticeably fresher. Dust, lingering odors, and that "stale house" feeling were dramatically reduced. Even after cooking or having guests over, the air clears much faster than I ever expected. What impressed me most is how **quiet** it is. On the lower settings, I honestly forget it's running, yet it's constantly cleaning the air. The Auto Mode is excellent—it ramps up when it detects changes in air quality and then quietly settles back down once the air is clean. The app is simple to use and gives helpful insights without being overly complicated. We purchased this for a large living area, and it has handled the space with ease. If you have pets, allergies, seasonal pollen, or just want cleaner air for your family, this unit is a game changer. The washable fabric pre-filter is a nice touch, and the overall design actually looks modern instead of looking like another bulky appliance sitting in the corner. The biggest surprise? We wake up feeling less congested, there's noticeably less dust collecting on furniture, and the entire house simply feels cleaner. Yes, it's an investment—but when you consider the quality of the air you breathe every day, it's one of the best purchases we've made for our home. If you're on the fence, stop debating. Buy it. Your lungs—and your family—will thank you.

Super quiet. Great app with easy controls. Easy to set up and connect to Wi-Fi.Extremely effective machine! I was sweeping an unfinished basement with the purifier nearby. The particle count spiked rather high (as expected) and within a handful of minutes it cleaned the air and was back to reading zero particles across all 3 measured sizes. This thing is absolutely amazing.

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.

Great product. Love the night feature that turns the lights off. Air feels much cleaner and the low hum is nice white noise.

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.

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.

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.

With wildfires in Alberta, I think my home needs purifiers. After spending a lot of time to investigate all the products in the market, I chose BlueAir. I need to say that my choice is great. It is movable, looks elegant, and functional. I already have it in my home for years and they are still very good. Oh, I say "they" because it is good so I purchase two.

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.
