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

I live in a home with a dog. I bought an additional one because the first one worked so well. No more of those flying things in the air that you can see when the sun streams in. The filters LAST and are not too expensive. They blend in with the furniture. It is a little loud when it goes through its filter cycle but Ill take it vs. smelling onions and cooking odors. Perfect item!

This is about the best in quality works fantastic.

I share an office with a smoker and was often hit by the smell of stale smoke when I walked in. The office itself also began to smell like smoke. I bought this filter for its size and look that blends in with the other furniture. I can still smell stale smoke when I pass my coworkers desk, but the smell no longer reaches my desk and the office is back to smelling like nothing!

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.

This unit turned on and got to work. Been on ever since. Kinda scared to open it up and change the filter. But no time like the present, right? Well, the outer washable filter slides right off. I dont think mine is quite ready for a filter change. Still mostly white. However, I could potentially see that changing the filter should be done by someone not quite so allergic to dust...and maybe not IN the room of the allergic person.

More than 15 days after receiving and using the Blue Air 411+, I purchased this 411 Auto model, considering the improvement in the air quality and enticed by a sale price and larger air volume capacity. Dimensions of this model is the same as the 411+, but performance is better. The One-touch control is more responsive than in the other model, as well as showing a seemingly more powerful fan: I tested it against the other model watching the movements of a piece of cloth using the max setting in both, and the Auto model beat the + model. The presence of the air quality sensor is impressively nice detecting some specs trapped in linen stored for a while in the closet: it immediately increased the fan speed to remove them. Also, I tried it moving the unit to the kitchen, responding very well to a little accident with the toaster oven. The only thing I dont like is the light from the AQI: it shines in red, orange, and blue brightly, the blue one shines when in the Night Mode, and we all have read a lot about blue lights affecting sleeping patterns. Had to place 2 pieces of post-it notes to decrease the intensity of the light, which is the only annoyance when using the unit in the bedroom. A positive is that the lights in the touch button dim completely when running in auto. In brief, this is a better buy than the 411+ from the pricing and performance points. As pointed in my review of the previously purchased model, air quality is really improved for both. This one is a very good Blue Air product.

Theres like this high pitched electrical whine? I think its coming from the plug, but not sure. Its pretty noticeable, more than other electronic whines, and unfortunately with both the unit and outlet right by my bed and in a super small room (7x11), its rough and sometimes I just have to unplug it when its not smokey, which is unideal. I cant really return it since the smoke season here hasnt let up yet and Im asthmatic, but I would recommend against this for a bedroom or a room you spend a lot of time of high pitched electrical noises bother you.

Im very ill and struggle with breathing sometimes. I have trouble cleaning my room due to my illnesses and I suspected the unclean environment wasnt doing me any favors either. I noticed that it was getting difficult to breathe specially when I was laying down. I would often wake up gasping for air. Ive had this air purifier over a week now and my breathing inside my room has improved greatly. If I have the filter at medium or full blast, Im not stuffy at all either. Im noticing Im not waking up gasping for air now. I cant believe the air my room was causing me so many issues. In fact, if I spend some time elsewhere in the house, my nose becomes stuffy again because my family doesnt use a purifier there. I have my purifier on all the time now. It has made some weird crackling noises only twice since I bought it. Its infrequent, though unsure what causes that. The auto setting is very quiet if filter detects the air is in good condition. Im able to sleep without issues while its on. If Im moving around my room, I set it to medium because I dont need it to be so quiet. I went with this brand because of how quiet it claimed to be compared to others available, the auto setting, and washable filter on the outside. It was a terrific investment for me and I only wish I had it since years ago. I never knew a device like this could really help me out with my health.

I didnt believe that home air purifiers would make much of a difference in my home. The AC is always on, there are 4 cats, several people, and someone is always entering or exiting the house. Dust and particles are always in the air. Ever since I got this Blue air filter, it has completely changed the air in my home. My eyes dont burn and itch at all whereas before, they did every day and I just attributed it to the 4 cats. Since I got this, Im a believer. I dont see dust in the air, there are no more little cat hairballs rolling around mimicking tumbleweeds in a desert. Im very happy with this and I got one for every bedroom in my home which has contributed to a better sleep, in my opinion. I thought this wouldnt make a difference. I was wrong. This is highly recommended.

excellent purifier
