MA-22 Replacement Filter

A genuine MA-22 replacement filter set should be used to maintain the effectiveness of the MA-22 air purifier. The True HEPA H13 filter removes 99.9% of particles down to 0.1 microns in size. Maintain your purifier’s Lifetime Warranty by replacing the MA-22 filters every 4 months or after 2,000 hours of use, whichever comes first.
