According to the EPA, indoor air is up to 5x more polluted than the air outside.
A pre-filter is an integral part of your AprilAire Room Air Purifier. This pre-filter helps trap the medium to large airborne particles that flow through your unit.
Without it, these larger airborne pollutants can clog up your other filters leading to inefficiencies and can even lead to an inoperable system.
Your pre-filter should be replaced every 6 months, at minimum, to keep your AprilAire Room Air Purifier efficiently trapping dangerous particles in your air, like dust, pet dander, viruses, bacteria, and mold.
Maintain Healthy Air with your portable air purifier pre-filter.
