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.”

FAQ
- MMWVerified Buyer1 week agoReviewingBlue Signature™ Nordic FogRated 5 out of 5 starsOutstanding!! And Beautiful!
This is my favorite brand and favorite model! Beautiful, quite efficient. The only thing that would make it better is if the light could completely shut off at night so I could keep it in my bedroom at night. There is always some light emitted. Perfect for the living room though.
- SBSean B.Verified Buyer3 weeks agoReviewingBlue Signature™ 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.)
- SBSean B.Verified Buyer3 weeks agoReviewingBlue Signature™ MidnightRated 5 out of 5 starsExcellent purifier
I have multiple Austin Air Bedroom Machines and IQAir systems at home. However, these new BlueAirs are my favorite purifiers due to being quieter + having an easy on, easy off washable pre-filter. My charcoal/big filters are on track to last ~18 months or so, which seems very reasonable. The units are also much lighter than other brands, so quite easy to move around. Finally, app connectivity is very helpful - another feature lacking for IQair and Austin Air.

Bomb! This is the best model of the best air purifier brand! If you can get it on sale get it immediately! I Wish I had waited a month to buy it because it went on sale! But it’s a beautiful and awesome air purifier! This brand was recommended to me by my coworker whose husband is a pulmonologist! They have them all over their large house! It’s quiet and very efficient! And beautiful! I wish Blue Air would make a purifier that you could shut the led lights off completely while running for nighttime use in a bedroom. All of them emit some continuous light. I keep this model in my living room.
