Roars and is very big - not for desktop!
[[VIDEOID:ab6117bb0d43f6b0a66978641de9d61e]] This “desktop” air purifier is entirely too large for a “desktop.”  Also, it roars loudly when you turn it on (see my video). We could not test the effectiveness of the purifier because it roared so very loudly. I wish I could recommend it, but I cannot.
