$75, Air Purifier Germguardian AC5000 HEPA UV
I have a Germguardian AC5000 air purifier for sale, it works great in all speeds and is only on its second air filter. It has only ever had OEM manufacturer filters in it and will be sold with one installed. The pre-filter is removable and washable as you can see in one picture. The actual filter beneath it is an activated carbon HEPA filter. It also has a UV bulb for killing bacteria in the air.
