The only filter I use!

The Puroair filter is excellent. It grabs and holds dust, dander and other contaminants that would otherwise end up in our lungs. The air in the room feels and smells fresh. It's hard to explain but the house just feels cleaner and safer. I have 3 of these Puroair purifiers and only use their filters. They are the best. They help prevent respiratory problems.
