The Austin Air Pet Machine Replacement Filter is engineered for homes with dogs, cats, birds, and other furry (or feathered) family members. This genuine replacement filter uses a specialized blend of impregnated carbon and mineral-based filtration. While the HealthMate Plus also uses an impregnated carbon and mineral-based filtration, the Plus is designed for broader chemical sensitivities. The Pet Machine filter focuses on pet-specific air concerns — using more mineral-based filtration and a different (proprietary) impregnated carbon formula that’s optimized to adsorb ammonia-based smells and neutralize persistent pet odors at the source. With Certified HEPA material rated to capture 99.97% of airborne particles down to .3 microns and 99% of airborne particles down to .1 microns, such as dander, hair, allergens, and airborne bacteria. This also helps protect the tiny respiratory systems of your pets! White filter is designed for White and Sandstone units Black filter is designed for Black and Midnight Blue units
