Air Purifiers for Medium Rooms, Bedroom, Kitchen, Cleans 1,858 sqft in one hour, HEPASilent Smart Air Cleaner for Home, Pets, Allergies, Virus, Dust, Mold, Smoke - Blue Pure 311i Max

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.

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...!

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.

The quietest we have found. High is a bit fluttery sounding. Indoor tobacco smoker in home, so got this. Tobacco smoker said that one family member needs it for different smoke. Ok? Works well, no matter. The young have app for it on their phones and thus they fiddle with it a lot. Works just fine on Auto setting when they are gone and I ignore it. It reports air quality to them constantly. How nice for them. Ahem. Seems like a quality item.

I’ve had this air purifier in my open plan living/dining/kitchen area for a year and I’m very happy with its performance. It cleans the air quickly from cooking particulates, smoke, etc. on the Auto or High fan speeds. I leave it on Low most of the time and it maintains the air at zero 2.5ppm. Changing the filter is easy. The app works well via Bluetooth if you want to schedule different fan speeds at different times. Would buy again.

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.

I bought this for our primary bedroom because it was the one room in the house that seemed to build up a lot of dust. We love this air filter. It has many settings and we mostly use the auto, as recommended. On auto and night settings it is wisper quiet which was very important because I am sensitive to sound while sleeping. It almost seemed like it wasn't doing anything until I started dusting the room and it kicked on. Also, the night setting turns off the front light which we like. The machine allows you to dim the lights which we keep on the lowest setting. This has made a huge difference in dust reduction. Additionally for an air purifier it's attractive. We will most likely purchase another on.

We have major sinus/allergy issues in our family. I found out that I needed to have my 3rd sinus surgery in 29 years and knew that I needed better filtration than just the heavier HVAC one we were using. After much research, I chose the BLUEAIR 211i Max, cleaning 3049 sqft in one hour. I have been using it for 11 months, 10 after surgery and am well pleased. I have experimented with the positioning of the unit and am happiest where it sits in the photo, as it is closest to the return air duct in the ceiling. I even ordered one for our son's house, on a different Coast, as they suffer the allergy curse as well. It runs quietly and effectively in the auto position for both households, revving up when a smell from cooking or opening the outside door often, etc. We are both well satisfied with this quality product!!
