YANKO DESIGN
“I tested it with kitchen odours 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.”

I had high expectations for this unit.
I believe it works well as intended, but it's longetivity is extremely poor.
Bought this May 26th this year and by end of August it is already dead.
I have purchased this to upgrade an old Honeywell unit, which is still working like a champ.
I am working with customer support team-while they are trying to be helpful, it is such a hassle.
Had to send receipt, serial number and such, and a video clip of the dead unit.
I purchased my unit directly from blueair.
