I expected my filters to be as wide as the Honeywell filters I am currently using.To my surprise they were undersized by about 1 inch. I ordered 20x25x4 and received 20x25x3. They fit, but a lot of air can get by because they do not fit snug.I will not be reordering. Id rather pay a bit more and get the correct size filter.
the measurements of my furnace and the measurements of the filter I ordered did not fit. I returned the filter to the address from which it was shipped from.
The filter came pretty quick however it was the wrong MERV rating from what I ordered. I notified the company and they immediately sent me a correct filter. Fits the furnace fine. For anyone who has not bought a replacement filter before, you can not rely on the standard filter size printed on the filter like mine is 25x20x4. You have to use the actual size usually also printed on the filter. The actual size varies a lot between manufacturers and is critical for a filter to fit.
