Common questions about 12x12x2

What is the actual size of a 12x12x2 filter?+

The nominal size printed on the frame is 12x12x2, but the filter actually measures 11.5" × 11.5" × 1.75". That undercut is intentional: it slides into your filter track without binding. Order by the nominal size printed on your old filter.

Which MERV rating should I pick for a 12x12x2?+

MERV 8 handles everyday dust. MERV 11 is our most popular. It captures pet dander and pollen. MERV 13 adds smoke and the finest everyday particles. When in doubt, call us. A real HVAC tech answers. Compare MERV 8, 11 and 13.

How often should I change a 12x12x2 filter?+

Every 30 to 90 days: monthly with multiple pets or allergies, every 60 days with one pet, every 90 days otherwise. See the schedule by household type.
