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 think the price point of this unit is great, but just didn’t quite air out our doggos dirty laundry. I tested the purifier by running our doggos outside in the dirty and enclosing them in our smallest Tom with the filter turned on high. The dogs coats were clearly dusty and dirty and I could see debris in the air. The filter would never change from the auto setting. Not sure if our unit was defective or if my test wasn’t the best. Overall didn’t think this unit was suited for what I needed it for.

I bought 2 of these because I wanted one in the bedroom and one in the living room. Living Room - I have noticed a dramatic decline in Dust in the room. Everytime we Dust, it would take about 2-3 days to have a coating of Dust again on tables, end tables, etc... (We have alot of electronics in the living room & 3 dogs) Now it takes about 11-13 days to be visibly on the same level as before. Bedroom - When we wake up we noticed a big difference after the 1st night with it. Our sinuses were alot clearer and breathing just felt better. May be a bit bias and maybe I was looking for it and noticed it but, we have been with it for a couple months now and I am still happy with them. I sleep with noise from a TV and the living room one also has a AC in the window near it so, I may not be the best to determine the noise level tolerance. When it is Red and using the high fan to really clean the Air, you will hear it though but, to me that is just it doing its job. Doesnt really bother me even when watching a movie or anything either. In conclusion - Noise Level - perfectly fine to me - Maneuverability - Soooo Easy to move where needed - Cleanability - Cleaning the exterior cover filter is as easy as vacuuming and/or tossing it in the wash. Interior HEPA filter needs to be replaced to be cleaned and right now its about 40 bucks for a replacement but, at about 6 months a replacement I feel it is still worth its while. Honestly, will be getting 2 more when we finish the basement.

I havent had these long so I cant speak to longevity, nor am I able to test air quality. That being said, I really like these units. I regret not picking up the larger one for my living room, but even the small one gets the job done. They are packaged well, no assembly at all (peel off a sticker and plug it in), with a simple one-button interface. They look good. They definitely are accurately kicking into high power/displaying poor air quality in that I can tell when I vape in the room and such they consistently turn up and flash the orange or red LED showing poor air quality. Some users may find them a little loud. When they are on high they are louder than my normal tower fans, but on low they are much quieter. As someone who regularly sleeps with fans or a/c, the noise level does not disturb me at all. If you are a very quiet sleeper, you may want to err on the side of caution with a larger size than your space demands- as the improved air maintenance should mean it kicking into high power less often. There may also be an option to leave it on low, but since it doesnt bother me I havent looked into it. All in all I would absolutely recommend these units to friends and family.

I was concerned when I bought these, some negative reviews about odor, too bright of lights, and loud fan noise. I tried them and am very pleased. No odor other than clean fresh air. Lights are not a bother at night and on low the fan can hardly be heard. On high it is louder but dont run it on high very long. I was also pleased with the automatic function. While cooking I took the lid off of a skillet and almost immediately the unit across the room kicked onto high. The other unit in the bedroom also kicked on high. They both ran on high for about 10 minutes, cleared the air, and back down to low. Breathing much better.

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!

These air purifiers work great. I live in a 560 sq/ft apartment with 1 cat. Ironically my cat has worse allergies than I do. I got 2 of the 311 autos, one for the bedroom and one for the living area. Since I started using them my cats snoring and sneezing has been much better. Allergens don’t bother me too much but I can also tell a difference in the air quality. I have noticed a big difference in the amount of dust in the house. The dust from cat litter is a big contributor and the purifier closest to the litter box will automatically turn the fan speed up after the cat has been scratching around in there. At first I thought the auto version wasn’t really necessary because I could just turn it up manually when I was cooking or something but the auto function really is nice to have. It reminds me of a canary in a mine shaft and will alert you to things in the air that you can’t see or smell. Overall I think these work well and are especially necessary if you have pets.

Liked how quiet it is

I bought this unit for my bedroom. I have a 2700 square foot home, large rooms and high ceilings. Room ratings are never large enough on purifiers, unless you have enough money to burn. My bedroom is roughly 225sq ft and I also have a large attached bath and walk-in closet... this unit works beautifully. The air was noticeably cleaner in minutes. On night mode...I live in a rural area, so there is no ambient sound to obscure it. Even sitting on my nightstand next to my head, I still cant hear it. Amazingly quiet mode. Ive gone through other purifiers that were less expensive than this one, but I can tell already this is much better quality. I wanted to give this a test run with the smaller unit before investing in the large one...I decided to purchase the larger unit for the main living area. This is a great unit. I will try to update after a few months of use, after having to replace the filter media, etc.

I’m impressed with this air purifier, it does a fantastic job in a bedroom and I suggest you leave it on 24/7 vs. just turning it on when you go to bed as the fan speed will automatically go to high & may impede your sleep but, just my opinion.

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.
