The filter is undersized and does not fit standard 20x25x4 filter boxes.

The second filter order fits my furnace. Even though both filters stated 16x 25x 5, the actual measurements are very different. In future I would not follow FilterBuy website instructions that state to round up the actual measurements, but rather call company and provide actual measurements.

This is my second order of 12 filters. I liked the white better for seeing the dirt, but I'm sure these will be just as good at filtering
