What is the function of an HVAC filter?

The function of an HVAC filter is primarily to remove dust and contaminants from the air that passes through the HVAC system. By trapping these particles, the filter helps to maintain indoor air quality, ensuring that the air circulating within a building is cleaner and healthier for occupants. This is particularly important for those with allergies or respiratory issues, as airborne pollutants can exacerbate these conditions.

Additionally, clean filters play a crucial role in the efficiency of the HVAC system itself. When filters are clogged with debris, the system may have to work harder to circulate air, which can lead to increased energy consumption and decreased system performance. Thus, while removing dust and contaminants is the primary function, effective filtration indirectly contributes to energy efficiency and the overall longevity of the HVAC system as well.
