without doubt the best air purifier!

Stylish design but lets unfortunately too much. To have it in the bedroom is out of the question unless you have poor hearing. Have an Electrolux EAP300 too, so I have something to compare with.
Believe the problem is that the fans are located, similar to those in computers, four. Then let it there for too, that just like a computer that sounds.
So now may be the lowest in the living room instead, hardly bearable either. To have it at a faster speed is totally out of the question, therefore, one might question how effective it will be, too.
Had returned it if I had not been quick and toss the box ...
Do not buy! Watch an Electrolux or Coway instead!
