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.
Review: One Outstanding Air Filter! - 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...!

### ⭐⭐⭐⭐⭐ Review
*by B***N on November 20, 2025*

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.
