The filters were way under
on July 16, 2020
Posted by: Anonymous
The filters were way under par compared to the original. Couldn't use them as they were under sized all the way around. I really thought I had found a replacement. GC

The 20x20x4 was so much under sized that there's air flow around the filter.

The original filter (16x20x4) fit
on July 14, 2020
Posted by: Edmund W.
The original filter (16x20x4) fit fairly snugly in the filter compartment, but this replacement of the same nominal size is smaller and has a lot of side to side play. It still functions, but I would prefer a tighter fit.

Filters good tight fit, however, would be helpful if they had a tab to grab on to pull the filter out. Ill probably have to cut hole in filters cardboard to get it out at its end of use

The cost of these filters is great and the size perfect, buying filters, is somewhat tricky as the actual size is different than the size on the box.

I change mine every 6 months; the one I remove is always filthy so I know the filter is doing the work
