Quality control could be better. The filter media on a couple of the filters I bought are bunched up and not evenly spaced for maximum filtration and air flow.

Pay attention to the Actual Size
on September 18, 2024

Frustrating that filters come in such random sizes. I was replacing some Honeywell filters and was happy to find filters with the same nominal size made in the USA. Stupidly, I didn't check the actual size. Even though these filters are the same nominal size, it turns out they were different enough so that they don't fit into my blower without allowing a ton of air to go around them, which pretty much defeats the purpose.

After an entire year of searching I finally found the right size filter for my Goodman furnace. And reasonably priced.

MERVE 11 A C FILTERS

The MERVE 11 A C filters are great. They trap much more dust, pollen, allergens in the air, a wonderful A C filter.

Fit perfectly for the Lennox unit. 25x20x5 has various actual measurements depending on brands. This fit perfectly.
