CZ-HM400-BP Austin Air
You should only need to replace this filter once every five years; it comes with a pro-rated warranty. The Pet Filter also comes with a new Permafilt Pre-Filter included.
The Pet Machine has a pre-filter to grab pet hair; 60 feet of true medical HEPA filtration to capture dander; and a special carbon blend tailored for pet odors, especially ammonia.
Four distinct filter stages address the complete spectrum of airborne contaminants: sub-micron particles, noxious gases, and chemicals. The Austin Air Pet Filter eliminates allergens and irritants specific to indoor pets.
This is the main replacement filter for the Austin Air Pet Machine.
