Verify your air cleaner frame size easily by locating the size label inside the c-channel at the top of your air cleaner. If the label indicates 20x25 or contains the part number 2025, these replacement pads will fit. The actual frame dimensions are slightly less than nominal, ensuring a snug fit.

Replacement filter pads are intentionally smaller to fit inside your air cleaner frame properly. This design prevents sizing errors and ensures optimal performance by accommodating the dimensions of the frame, not the disposable pad itself.
Exactly what I hoped for
Instantly felt happier about the air in my house, just this weird little sense of relief every time I walk in now.
Better than I expected
Our hallway used to have this faint musty smell no matter how much I cleaned, and my allergies were always acting up. Swapped in one of these pads and within a day or two the smell was basically gone and the air just feels fresher. Super happy I tried these instead of calling someone out to look at the system.
