Sure, ya it's the Winix 5300. Bit confused on the price though, I remember it being significantly cheaper than the prices I see for it now. I do like it though (one note: I never use the "plasma wave" or whatever that is, just the filtering).
If you go on Amazon they have many HEPA models that advertise their decibel levels explicitly. If its listed as going down to the low 20s in decibels it will be almost completely silent.
