30x30x1 MERV 11 Pleated Air Filter

perfect fit quick delivery

The filters were fine,I'm satisfied

Excellent fit in the return. The packaging was in good shape.

Exactly what I needed at a fair price and fast shipping. Couldn’t ask for more.

I've used fiberglass filters for years, but they never seemed to catch much (ceiling return air A/C). The old frame was flimsy, which allowed me to squeeze it into a frame holder of the exact same dimensions. The new one is 1.4' undersized all the way around, so it went in easily with no gaps where it lies against the face of the enclosure. That frame is stronger, so it doesn't need the netting on the downstream side that my old filters used. The filter material is denser and the pleating provides more surface area so the air volume through it seems to be about the same. I'll see how it looks at the end of the cooling season here, which runs about 120 days, with the early and late weeks representing only occasional usage.
