Common questions about 12x20x2
What is the actual size of a 12x20x2 filter?+
The nominal size printed on the frame is 12x20x2, but the filter actually measures 11.5" × 19.5" × 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 12x20x2?+
MERV 8 handles everyday dust. MERV 11 is our most popular, it captures pet dander and pollen. MERV 13 adds smoke, bacteria, and virus-carrier capture. When in doubt, call us, a real HVAC tech answers.
How often should I change a 12x20x2 filter?+
Every 30-90 days. Monthly if you have pets or allergies; every 2-3 months otherwise. Our subscription handles the schedule for you.
Is a 20x12x2 the same as a 12x20x2?+
Yes, 12x20x2 and 20x12x2 are the same filter; the dimensions are just written in a different order. This filter fits both.
