BLUEAIR Bedroom Air Purifier, Air Cleaner Dust Pet Dander Smoke Mold Pollen Bacteria Virus Allergen, Odor Removal, for Home Office Kitchen, Washable Pre Filter, HEPASilent, Medium Room, Blue 311 Auto

We had a catastrophic flood in the basement of our house which caused dust, dirt, and mildew to permeate everything. A friend suggested this air purifier and we could not be more satisfied. Right now it sits in the kitchen - near the basement stairs - and, when the workers come and start hammering, sawing, etc. it immediately turns itself on to a higher speed. Very impressive. We will be buying more of these for other areas of the house.

This air purifier is quiet and unobtrusive. There isnt a light to indicate that its running after youve initially turned it on and Ive stumbled over it in the dark. It was highly rated on many lists which is why I purchased it. My only complaint is you get no indicator of air quality. My other air purifier has a light indicator of air quality. The filters are also pretty expensive.

This air purifier is so quiet, if I dont see the blue light I think it is off! We have a small apartment and this machine keeps odors at bay. I plan to buy my second one for the bedroom.

Its nice, but that sticker on the top of the power button when its new is quite difficult to remove

I purchased this because every morning I would wake up very congested. I placed the air purifier in my bedroom and no longer have the morning congestion.

Have a small 45 year old 1200 ft cabin in the woods and shopped for air purifier that would work with seasonal pollen, cat hair/dander from two cats( and litter pan odor), woodstove smoke/ash, occasional kitchen cooking pollution. Lots of claims out there in wide range of prices...this one,far from cheapest, or priciest, seemed to offer quality needed to address enviromental indoor air polution. Liked 2 phased filtration,charcoal for odors, and that filters lasted 6 mo rather than 1. Located in sleeping area,quiet operation a plus. Have had unit for 6 months now, and just replaced filter,which was autoshipped from mfg,as i did not trust the cheaper knockoffs that would fit,but questioned getting same results. Set filter replacement auto ship, was favorably impressed to speak with rep in understandable english without waiting on perpetual hold,and registered warranty at that time. First time i fried bacon,smoke carried into living area and demonstrated the sensor/detector in action,works as advertised. This unit has meaningfully enhanced indoor air quality in times of ever increasing pollution, providing better quality of life/living... highly recommend.

I bought the 311 auto after much research and no regrets! Have already noticed a difference in my allergies in a few days of use. Going to buy another unit for the guest bedroom.

This is a big air purifier, I figured because it was a larger filter it would last. I have smaller ones (different brand) that last much longer. I have this in my bedroom and the filter is already plugging up. 6 weeks. Not worth the money and new filters are very expensive.

I love this thing. Ive used the 411 for years, and actually treated our home to a second one for the living room next to the dog toys, which can collect dust, dander, and everything else that goes along with having a shedding outdoor pet. Its whisper quiet (so quiet youll wonder if its working -- but I promise you, it is!) and easy to move around if, say, youre painting a room for a day. My only balk with the product is it has a light that stays bright as long as its turned on. As a light sleeper, this can be distracting. I fixed it by taping over the light. But Id love to see a dimmer or auto-off mode after its been running for 5 mins. Otherwise, a terrific product at a fraction of the cost of competitors. Especially with the northeast coated in smoke right now, I can breathe easy knowing my family is surrounded by quality air. Stock up on filters, too! Youd be surprised how infrequently people change those things, and thats what makes these things work so well.

I have a typical ceiling fan in my 13’x15’ ft bedroom, fan set to about medium, pulling upwards for winter circulation. Fan is in opposite corner of where I sit and vape and read and write on this thing, and within like 5 seconds of exhaling a cloud of vapor the fan on the air cleaner ramps up, gets rather loud honestly, though I don’t mind it. It very clearly lets me know it’s working and how sensitive whatever pollution sensor is inside it is. So far, I’m quite happy with it and from what I can tell so far as to the condition that the filter is in, that it’s doing a heck of a job too… we’ll see if it lasts 6 months. ;)
