Air filters and filter media for residential and light-commercial HVAC systems, including charged-media filters, filter inserts and the cabinets that house them.
Order by the exact dimensions of the existing cabinet or rack — nominal sizes and actual sizes differ, and a filter that is close but not correct will bypass air around the media instead of through it. Filtration efficiency is a trade-off: a denser filter captures more but restricts airflow, and going beyond what the blower was designed for reduces system performance.
