What to know before buying
- The listing uses 16.5x21.5x1 as the nominal size and gives actual dimensions of 16.50 x 21.50 x 0.75 inches. Match the actual size to the existing filter and check the HVAC maker’s MERV requirements. The listing's claims about capturing 90% of dust, lasting three times longer than fiberglass models, and 615 cfm are manufacturer claims, not independently verified performance figures.
