Choosing A MERV Rating
MERV 8 is a common residential choice for dust and pollen. MERV 11 and MERV 13 add stronger particle capture for homes that need higher filtration.
How do I find my filter size?
Check the size printed on the existing filter frame, then compare the nominal size with the actual dimensions when available.
