Air Purifier for Small Room, Bedroom, Home, Cleans 926 sqft in one hour, HEPASilent Air Cleaner for Pets, Allergens, Virus, Dust, Mold, Smoke - Blue Pure 511i Max

So far, this air purifier has been excellent. The app is very detailed and easy to use, and I like how it explains the readings and what each level means. The technology is great, and the system actually adjusts on its own when windows are open, while cleaning, or when cooking. I do prefer the smart display on the larger unit, but this definitely gets the job done for bedrooms. It runs much quieter than it sounds in up-close videos, even on higher fan speeds. The air feels noticeably cleaner. We have noticed a difference in stuffiness and allergies. We have one large unit for the main floor and two medium ones for bedrooms. I plan to buy at least one more large and three more medium units because they work that well. Great value for the price and quality. I run these all the time at the moment, but love the option to schedule. The size is perfect for a bedroom.

I read a ton of reviews, this one seemed to be Solid. App was easy to install and set up. Provides air quality statistics and other information. Provides plenty of options. Very quiet on the lower settings. The # 3 is louder that the rest, but never obnoxious. The air in the room is noticeably cleaner. Before I started using this, the dust would build up on all the surfaces. Should be a huge help when allergy season hits in the spring. Now there is hardly any dust at all. This is a very nice looking unit. Small size works well in small rooms and even on counter tops, etc. Well worth the price, would buy again.

This review is for the two 211+ (not automatic) units I've had since 2020. Initially, I purchased these after the devastating wildfires in the Pacific Northwest when people were sealing off their windows with tape and using box fans with furnace filters on the back in a desperate attempt to remove the wildfire smoke that had infiltrated all our homes. And with three not-small dogs anyway, it just made sense. Five years in now, I can say that I have been EXTREMELY satisfied and impressed with both of my BlueAir 211+ air purifiers. The initial setup and subsequent maintenance is effortless. You take it out of the box, put it's little prefilter on the base, drop in the air filter, pop the top of the unit containing the fan back on, and forget about it for a while. I replace the filters about every 6-9 months, and wash the prefilter cover way less often than I should considering the amount of dust it very efficiently sucks up. With one in the living room and one in the main bedroom, I have both ends of my home more than covered, as with the two combined, they are rated to filter more square feet of air than the size of my house. I've literally had them both running *nonstop* for the ENTIRE five years I've had them, and haven't had a single problem with either of them. Once in a while I'll come home to find that during rambunctious play or a particularly assertive barkfest at a delivery person, a dog butt has grazed the power button on the one in my living room enough times to turn the unit off. Kept on low, the fan is incredibly quiet and barely perceptible if at all. The only reason I notice it's been turned off immediately when I come home because the living room smells noticeably different when the purifier hasn't been running; the air smells comparatively stale and decisively more like dog than when it's running. I also noticed and appreciated their impressive performance in 2022 when once again, my city was infiltrated by wildfire smoke from fires that were literally hundreds of miles away. The air quality outside was dangerously high, but inside my home, per my thermostat app, the air quality was normal. This was particularly impressive considering it was literally snowing ash outside, harkening back to the much closer terrifying fires of 2020 that nearly breached city limits. Having these in my home gives me piece of mind that I'm about as protected as I can be against airborne pollutants like smoke, dust, pet dander, and the occasional cooking-adventure-gone-awry. Eventually when these do stop "biting the dust" as it were, I'll gladly replace them with the newer model that has the power button on top and the ability to turn off the power indicator light, which I desperately wish my older model had for my bedroom unit.

I’ve been using this BLUEAIR air purifier in my bedroom and small living space for a few weeks now, and it’s been a noticeable improvement. The unit runs very quietly — even on higher settings it’s much less disruptive than I expected, so it’s easy to leave it running overnight or while working at home. It does a solid job of cleaning the air quickly; it claims to cover up to about 926 sq ft in one hour, and I definitely noticed less dust, fewer odors, and crisper air within that range. Setup was easy and the controls are intuitive, so you’re basically good to go right out of the box.

Works well right out of the box. This the 4th one of these that I've purchased and all are still running strong. I have several family members suspectable to airborne allergies and these help quite a bit. We use the medium speed to keep down the noise and they run 24X7.

I purchased the large unit for my great room and was so effective i purchased this smaller unit for my bedroom. It is honestly so quiet I need to put my hand over the top at times to ensure it is running. :) This device is so effective it took away a new cough I developed after moving into a newly built home - the cough was gone within a week.

Great air filter that is high quality and the App is a good addition that allows you to see current air quality and suggests when to change your filter. Purifier is very quiet when running at low setting and I appreciate that you can adjust the light brightness at night in the bedroom.

Have already noticed the cleaner air in our bedroom. This product is quiet, value for the buck and all good. So many have reported buying more. I will be buying more for other parts of our home.
