CZ-HM400-WP This is the main replacement filter for the Austin Air Pet Machine.
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.
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.
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.
