Wrong size 4x20x25

Quick service but the actual dimensions are wrong. The fit was incorrect, too small. Had to stop service and go back to the big box store filters.

Good Filter just is not 20x20x4
on April 28, 2026

Purchased these filters to replace the original Honeywell filters and these are significantly smaller. They are not close to 20x20x4. They just flop around in the filter tray. These will not work for my application.

The filters are ok , quality is very good, the only problem that I have is that the filter that my furnace uses is 16x25x4 the ones I received are smaller. Still working but I have to do some adjustments.

Thickness of the filter is not close to the advertised 4inches, so unsure of performance as fit is inaccurate.
