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

This air purifier works great and is very quiet. Perfect. HOWEVER - Amazon doesnt sell replacement filters for it. Had I known that in advance, I would have picked a different model.

Being an extreme allergy sufferer, this is not my first trip to the air purifier rodeo. After reading reviews, I decided to try this unit out. It has performed wonderfully so far. And is by far one of the quietest units I have owned. The fact that it has an automatic air sensing function and will run accordingly is also a pretty great feature. So far my air quality is better as is my breathing and allergies

Purchased this air filter to install in a child’s bedroom. The low sound level and compact size make it great for smaller rooms. Pros: - It’s A very quiet air filter even with the fan on full speed. - The Gray cover is great at hiding the dust that builds up between washings as the air filter is used. - It looks good in the room and is not an eye sore. - Auto Setting is a convenient way to run the air filter. As it senses changes in the air quality the fan will increase circulation and air filtration. - LED indicator will change as the sensors pick up changes in air quality. Cons: - The Gray cover goes directly over the filter membrane. There is no plastic sub structure. That means if it’s in a child’s room and child knocks something into it, it could dent or damage the filter itself resulting in the need for a replacement. - Without constantly referring to the manual it’s difficult to know what setting it’s on. This can be rather problematic if a child continues to cycle through the settings. Would I recommend it to a friend: Yes

Its compact, light, and quiet

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.

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.

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.

excellent purifier

My husband was becoming like all of the seven dwarves… Sneezy, Snorey, Wheezy, which was making me Grumpy. We needed help with the air in our room. We got the bedroom size purifier and literally the first night we both slept like a Princess. It worked so well to purify and cleanse our space and didn’t take long at all to work. The sound is very quiet when it’s on the lower settings. It’s a little louder when you turn it to the highest setting but it’s almost like a nice sound machine. The size is great, it’s easy to move, and we’re thankful for a better night’s sleep than we’ve had in weeks since seasonal allergies picked up. Highly recommend.

This is about as good as youre going to get if youre looking for a small filtration unit for a room. This is a good quality assembly and the filtration is very effective for the size of the unit. I have this one and a larger one made by the same company that is several hundred dollars, and both perform very nicely. I recommend this smaller unit if you have a lot of rooms that are spread out, its probably better to have several of them. The sound of the fan is very steady, clean, and low. A consistent sound that is desirable as white noise. So it actually makes for a good white noise generator for sleeping, etc. Ive seen those going for $100 that are less quality in the white noise department and dont even filter the air.
