Seems Okay
Just plugged this small air purifier in 2 days ago.  Seems to be deodorizing (smaller bathroom); will have to wait and see re:  other claims (i.e. killing germs, freshening, etc).  There is the "white noise" that other customers have mentioned, however, I don't find it to be too annoying now that a couple of days have passed.  Yes, item is on the pricey side but I am open to ordering at least 1 more if it proves itself worthy.
