The filter was made smaller than the 20X25X4 by about a half inch all the way around, so it did not fit exactly into my furnace filter area (left a gap where air could go around it). I ended up cutting the edge off of my old filter and putting the new Tier1 inside so it would fit exactly.

These filters are advertised as 20X25X4, but fall a little short on each measurement, especially the 4" depth. We had to shim it so that it fit properly in our system. I like the price, but will not buy these again.

Fit good. Seems to be performing adequately for a fraction of the price. Thanks
