I have used ozium as well, have the ionic brezze (def not worth half what it costs)
I have a relaxed situation so not to bad for me, but don waste your money on the ionic breeze you see on tv

I have a holmes filter works ok but ozium and the method expressed by mr spicoli, that has worked for me as well, try to take small hits and hold it in, take your time and blow it out the window with some ozium but that maybe a little obvious your room always smells so fresh lol
