Common questions about 24x30x2

What is the actual size of a 24x30x2 filter?+

The nominal size printed on the frame is 24x30x2, but the filter actually measures 23.5" × 29.5" × 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 24x30x2?+

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 24x30x2 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 30x24x2 the same as a 24x30x2?+

Yes, 24x30x2 and 30x24x2 are the same filter; the dimensions are just written in a different order. This filter fits both.
