HVAC filter
Duct debris catcher
An HVAC filter is a replaceable component in heating, ventilation, and air conditioning systems that traps dust, pollen, and other airborne particles as air circulates through the system.
Filters vary in efficiency—measured by MERV ratings—from basic fiberglass screens to high-efficiency models that capture microscopic allergens.
