20x25x4 filters fit loosely

FilterBuy clearly lists the dimensions. Be aware these filters are not as wide or tall as others such as Honeywell. I am using the first one and hope the loose fit does not negatively affect static pressure, a measurement my system makes to determine air flow restriction to send an alert to change the filter. I can not tell if these filters are electrostatic charged, either, like the Honeywell, but they do not appear to be, so I am unsure how efficient these MERV 8s will be compared to Honeywell.

When I go to the store and buy a certain size filter, I would expect these to follow that standard sizing.

The Filtrete filters i bought previously were of the same nominal size but actually were too large for the filter chamber on my furnaces. Filterbuy filters are just the right size. We'll see if they last for as long as a year before they need to be changed.

Filterbuy was the only company that had the odd size filter we needed. What a relief!

Filters are smaller then 20x25x4 so loose in our furnace and letting in more dirt and dust into our new furnace.
