Keep your 4-in-1 AirProtector performing at its best and send allergies packing with the Replacement H13 HEPA Filter, which works to trap dust, pollen and other nasty particles so you can breathe easier.

Two-stage filtration with a fine preliminary filter to capture pet dander, dust, hair, mold, fungi, and larger particles, and a True HEPA-13 Filter to effectively remove pollen, allergens and PM2.5 and all harmful fine particles in the air as small as 0.3 microns in size.
It is recommended to replace the filters every 3 to 6 months, depending on use.
