I’m really delighted with my BLUEAIR Blue 311 unit. I went into the purchase expecting false advertising and was very happily proven wrong day 1. I’ve had it over a month now, just enough time to get to know it. When I light up in the house at night it turns up it’s intake, and the little light changes from blue to orange. That’s fantastic but even more impressive is that it somehow detects when my cat goes in the cat box and up it cranks. It has a bit louder sound in super clean mode, but it’s not very noticeable. I remember the first time I noticed it had cranked up and said to my hubby, that’s the air filter? I thought maybe he left the faucet on. Very quiet. Allergy season has been slow to bother me this year, eliminating my need for antihistamine despite the fact that my car has a green coating from our neighbor’s pine tree. It’s not a small unit, about 2 feet tall by 1 foot round, you need space for it. I didn’t mind, odors bother me more, I made the space for it. If you want an excellent air filtration unit you will love this one.

This does a great job of removing odors from my home. It is not bulky and will purify an entire floor

The one I have in my bedroom worked so well I brought another one for the living room. I did not believe this would work until I had to change the filter which was black when I went to change it. The only question I have is why does the top start to to have discoloration? It was white but now starting to turn a smoky color?

UPDATE: I put this air purifier in the garage, and it is noticeably reducing the musty smell, so I am happy to have it, even though I found it unusable within the house. Earlier review: I used my BLUEAIR 311 in a 9x11 bedroom for four nights and awoke with progressively worse headaches each morning, until I realized it must be the air purifier and turned if off. No more headaches. So, I moved it to my family room, thinking it was better suited to a larger room. I dont spend much time in that room, but there is airflow to the rest of the house. A couple weeks later, I wondered if the eye redness and itchiness I was experiencing could be due to the air filter. Turned it off. No more eye redness and irritation. BTW, I dont have allergies. I bought this for house guests who are allergic to my cats, but thought Id try it in my own room. This was an expensive machine that I cant even donate or give away in good conscience, knowing the health effects it could have.

My wife has horrible allergies and this little guy keeps our bedroom air super clean

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.

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.

Its compact, light, and quiet

Works great in the bedroom.

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.
