Blueair is the only line of air purifiers with a customizable, washable fabric pre-filter.

Noise refers to the dB(A) difference in acoustic power. **When similar CADR was measured, Blueair models with mechanical and electrostatic filtration achieved less noise with less energy than same models with only H13 HEPA mechanical filtration. ***Tested PM 2.5 (0.1 - 2.5 microns) up to 90min in a 30m3 room.

Review: Air purifier. Excellent for carpeted homes & people with allergies, dust, dander, pets, & smells. - 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.
Review: Great Product, Filter Lasted Longer Than Advertised - I purchased two of these Air Purifiers in April of last year (currently February, ~10 months later) and am extremely pleased with the results and effectiveness of the product. I live in Brooklyn, NY in a railroad style apartment (one side facing street near-ish a busy road, the other side facing an interior courtyard) and I purchased two 311i Maxs. One is in the the threshold between the kitchen/living area and bedroom area and the other is in the main "bedroom" that faces the street. The threshold between rooms is high traffic, so lots of dust and particulates get swept around when I walked between the rooms of the apartment. Immediately I noticed that the dust accumulation in the living and bedroom area became much more gradual. The purifier itself also traps a TON of dust clumps on the cloth outer filter that needs to be cleaned periodically but I am happy to know that it is certainly doing its job. The bedroom purifier also is doing well, but its a much lower traffic area of the apartment so it doenst need to be cleaned as often. The advertised filter live is 6 months. However, after 10 months the high traffic air purifier's filter is just about at 15% and I purchased a replacement. For context, I run it constantly at its lowest setting and have it automatically adjust to a medium high setting for two hours each evening from 5-7pm (this is usually when I am cooking and honestly, not even sure if this is necessary). I am extremely impressed with the durability of the filters in this capacity. Noise wise, I couldn't be happier. They certainly have gotten marginally louder over time (likely due to filter age) but really not bad at all. My (aging) refrigerator's cool cycle is louder than these things. I'm an audio engineer so I use my ears for a living and am particularly sensitive especially when I am working or trying to go to sleep. Not only is the purifier's noise imperceptible from more than 10 or so feet away, but I have on running all day in my studio where I work and I don't have to turn it off except to record exceptionally quiet sources. To be fair, this is all on the lowest setting. The higher settings are certainly noticeable, but about the same volume as my Mideas air conditioner. The app also works great. When there was renovations happening in the apartment below mine, I was able to periodically check in on the particulate levels while I was out for work and adjust the purifiers intensity as needed to make sure no unwanted drywall or wood dust settled in my apartment. The indicators on the units are helpful as well to see the air quality change when cooking or lighting...erm "incense" and know that the purifiers are doing their job and keeping the house clean and odor free. You can have the filters auto-set depending on particulate levels but honestly, they work so fast at the lowest setting I rarely find myself manually upping the intensity of the fan unless there is a serious cooking/smoke mishap or something similar. You're probably better off just keeping them on low 90% of the time. Recommend these to folks all the time as I do to you, dear reader.

### ⭐⭐⭐⭐⭐ BLUEAIR Air Purifiers for Large Rooms, Cleans 3,048 Sqft In One Hour,
*by P***G on August 28, 2024*

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.
