Seems to be a good filter. Haven’t had it in very long, but seems to do a good job so far.

Size is smaller than listed
on June 29, 2026

I ordered the 18x24x1 size filter and the fit is not proper. It appears your filters are about a 1/4 to 1/2 inch smaller than listed. Flimsy material also, very dissatisfied and will not be purchasing again.
