BLUEAIR 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

It isn't often a product like this surprises me, but the quality of this device is amazing. I have the higher end device which can detect PM1 material, and the device can detect when the window is open with the slight change in air quality. I have had someone pass gas, and the air filter has detected the change in air quality. I have cooked bacon, where the grease and fumes are hard to exhaust outbound, and this device does a great job in cleaning the air after cooking. My filters are working overdrive, so I would tell any other consumers to expect to replace filters every 4-5 months instead of 6. Also, do not purchase third-party replacement filters as they are paper thin and do not work. Wait for the Thanksgiving and Christmas season, and purchase multiple filters when they go on sale. The air flow is impressive. The fan is quiet, even on the highest setting. The device does connect to WiFi (optional) if you want to set schedules throughout the day. I personally just run my device 24 hours. The value I paid for mine is great. I purchased my device about six months ago during the Black Friday promotion, and ended up purchasing a second one for a family member.

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.

We've had multiple versions of the 400 series Blue Air Filters over the years, and while they have continuously updated the product, this latest version was a substantial improvement. They added an app which is actually very well designed and provides useful controls and additional info (versus many product apps which simply do the same thing as the controls on the product itself). It works very well with Alexa. Finally, they clearly listed to customer feedback. One frustrating aspect of much earlier models was the fact that there was a light on the product that you could not turn off when it was on (I placed a large coin on it every night to block the light). It was annoying in a bedroom where you wanted total darkness. More recent versions of the 400 series had the light turn itself off after a few seconds - presumably folks had complained and to their credit they made an obvious improvements. This newest version finally gives you full control over the light (not just on/off, but full 1-50 intensity variation). I don't usually write product reviews, but I was really impressed with how much an already good product was improved upon - all for pretty much the same price adjusted for inflation as when I bought it a few years back. Highly recommend this product.

I got so tired of reading conflicting reviews on all the many different medium room size air purifiers that I finally settled on this model. It seems a bit pricy compared to many of the others of comparable size, especially since all of these tend to have a prefilter, a paper filter, and a charcoal filter layer. All these air purifiers are essentially the filter powered by a fan pulling in the air through the filter and then sending the filtered air out. Logic would dictate they are all doing the same thing. The plusses for this model: This model is ready to use out of the box and has a very quiet fan. You get added features if you connect using your phone app. Downside: unit is very finicky about connecting to your phone. I had to try several times. It does tend to make the room feel cold, and filter replacements are expensive and non-OEM filter choices are extremely limited.

I have used this unit for several years. I literally have no complaints. It looks good, it's quiet, the app is awesome, the filters are reasonably priced, and most importantly... it works. The filters are clearly working, as seen when replacing them, The washable cloth pre-filter is simple genius. Plus you can get different colors, which is also nice. The air monitoring works flawlessly. It's surprising the times that it ramps up the speed to clean the air. You wouldn't think that microwaving popcorn would spew micro particles (presumably oils) into the air, but it does and the filter kicks up a notch until the air is clean. Highly recommended product.
