How does an air cleaner work?

Air is cleaned by an HVAC-installed air cleaner while the HVAC system is on (actively heating or cooling the house, or while the blower fan is on) because it moves air through the air cleaner filtration system. As the air passes through the air cleaner and the filter media within, it traps the unwanted particulates, allergens and contaminates. The air leaving the air cleaner after passing through the filter is free of particulates, allergens and other harmful contaminants. UV Purifiers (as found inside the TERSus Air Cleaner) utilize germicidal irradiation like the sun outdoors to eliminate mold, bacteria, germs and viruses from the air.
