Common questions about 8x36x1

What is the actual size of a 8x36x1 filter?+

The nominal size printed on the frame is 8x36x1, but the filter actually measures 7.5" × 35.5" × 0.75". 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 8x36x1?+

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, and it's fine in modern systems (post-1995 blowers). When in doubt, call us, a real HVAC tech answers.

How often should I change a 8x36x1 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 36x8x1 the same as a 8x36x1?+

Yes, 8x36x1 and 36x8x1 are the same filter; the dimensions are just written in a different order. This filter fits both.
