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

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.

Filters OK but cardboard was smashed and the filter frames were bent down. Think they are able to be used.
