HVAC filters are removable media placed in a heating or cooling system’s air handler to remove dust, pollen, and other particulates from circulating air. They are critical for protecting equipment, improving indoor air quality, and system efficiency. Filters are rated by MERV (Minimum Efficiency Reporting Value), from 1-16 for residential use, with higher numbers capturing smaller particles. Key factors: The filter must match the exact size (nominal and actual dimensions) of your system’s slot. A higher MERV rating improves air quality but can restrict airflow if the system isn’t designed for it. Regular replacement (typically every 1-3 months) is required to maintain performance and prevent strain on the HVAC unit.
