YANKO DESIGN
“I tested it with kitchen odors while cooking, and within about 20 minutes of running the air purifier, I could smell little to nothing. I find that astonishing. I've used other air purifiers before, but this one does the trick.”

- SBSean B.Verified Buyer2 months agoReviewingBlue Signature™ Large Nordic FogRated 5 out of 5 starsUnit is whisper-quiet
As you can see in the video, the unit is whisper-quiet at night. It has replaced an Austin Air Bedroom Machine that was much, much louder even on the Low setting. I can now sleep better, thanks to BlueAir's quiet but effective filtration. I also like the ability to auto-schedule Night mode on/off through the app. (E.g. On daily at 8pm and Off, turning to Auto, at 8am.)

This is my 6th Blueair and by far the best. Highly recommend. Impressive!

Loving my new BlueAir signature air purifier so far! It looks so sleek, doubles as a light side table, and is almost silent on the lowest fan setting. I love that the screen can be dimmed or locked so it appears to just be a table, and the app control and air quality info/scheduling is great too. I’ve mostly used it in eco mode for energy efficiency and really like it so far- the easily washable pre-filter is really convenient. I’m not sure how much replacement filters cost yet, but the app keeps track of the filter use and estimates lifetime for you. The cylindrical design isn’t the most space efficient, but since it can fit in with a room pretty well, it’s easier to have it centrally located to optimize air filtration- if you have an outlet nearby.

We love this air purifier. It’s perfect for my someone with allergies & 2 dogs. It’s also stylish & fits in with our living rooms design!

10/10. I have severe allergies and the Blueair Blue Signature makes a drastic difference in my symptoms. I love that it has a huge radius that it covers, so I’m able to take care of the entire downstairs of my home. It’s quiet and produces a calming light white noise. Clears up food smells fast as well.
