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.

Exactly what I was looking for. Fit perfectly functions better than the higher priced ones from the box stores. And way cheaper than the box stores for sure.
