Airthereal APH260 + APH320 Replacement Filter | True HEPA | 1-Pack or 2-Pack
The APH260 and APH320 also run on this original True HEPA filter — the standard-grade option alongside the medical-grade H13 version, sized to fit either purifier.
The build follows the same three-stage logic: a fine pre-filter, a True HEPA core, and an activated carbon layer working together to capture what's actually in the air. This version removes 99.97% of airborne particles down to 0.3 microns — dust, pollen, bacteria, mold spores, pet dander, smoke, and VOCs — the True HEPA standard, one tier below the medical-grade 0.1-micron filter also available for these models. For most households managing everyday allergens and odors rather than the finest particulate range, it's the filter that does the job without paying for a grade beyond what's needed.
Replacement is straightforward: power off and unplug the purifier, remove the front shell, take out the old filter, and unwrap the new one before installing it with the pull-tab facing outward. Close the front shell fully — the unit won't power on if it isn't seated properly, a built-in safety measure. Press and hold the FAN and TIMER buttons simultaneously for 3 seconds to reset the replacement alert. The PM2.5 light turning red and flashing is the unit's own signal that it's time, typically every 6 to 8 months, alongside the earlier signs of increased noise, decreased airflow, clogging, or returning odor.

Native Manor Note: Not every household needs medical-grade filtration to breathe easier — most just need the True HEPA standard doing its job consistently. This filter fits the APH260 and APH320 exactly as designed, catching dust, pollen, dander, smoke, and VOCs at the 0.3-micron threshold that covers the vast majority of what's actually in the air.
