The all-in-one replacement filter for the Saqua air purifier SAP-22.
The SAP 22 air purifiers filter viruses, bacteria, allergens, particulate matter (PM0.1), pollen, pet dander, cigarette smoke, mold spores, volatile organic compounds and home odors.
This filter should be changed annually unless the unit indicates earlier that it should be changed. This depends on the amount of contamination in the room where the air cleaner is used.
