Description
FilterLock® by AllergyZone™ seals furnace and air conditioning air filter slots to reduce utility bills and improve indoor air quality. If not properly sealed, harmful airborne contaminants can enter the heating, ventilating and air conditioning system (HVAC system) through the filter slot/door and bypass the air filter completely. This HVAC filter slot cover eliminates unfiltered air from leaking into the furnace or AC system through the filter slot in air filters.
