The Filter King 24x30x1 is a pleated 1-inch furnace and AC filter rated MERV 13, sold in a 4-pack. MERV 13 captures fine particles such as pollen, mold spores, pet dander and smoke, which is a step above the common MERV 8 and MERV 11 filters many homes use. The nominal 24x30x1 size is larger than typical return grilles, so it fits big HVAC systems and air handlers. Filter King says each filter lasts up to 90 days, and buyers rate it highly.

Buyers rate it 4.8 out of 5 and mostly praise the filtration and the fit once they check the actual dimensions. Complaints center on the nominal-versus-actual size gap and on airflow in systems not built for MERV 13.
