Frost KingAir Conditioner Filters, 15 in. x24 in. x3/16 in. , Open Cell Foam[Amazon-developed Certification] Compact by Design

Perfect replacement. Very easy installation. Each envelope contained 1 sheet of thin foam, which was more than enough material to replace filters in 2 of my through-the-wall air conditioners. This foam filter is thin; you can actually see through it. For cutting the correct sizes, I used the original filters as templates. With these new filters in place, my air conditioners are now working fine, blowing and cooling Dust Free. The new filters did not impede air flow.

This is for my Furrion AC unit in my camper. These are very compatible to what was in there from the factory. As noted, you have to cut them to size. They are easy to cut, and one package can accommodate two uses or two AC units like I have in my camper. Great value for the price.

Lo puse debajo de mi laptop y funciona muy bien, no corta el aire y filtra cierto porcentaje de sucio, pelusas y polvo

I like these. I know, they’re old school. I use them as a kind of prefilter over the plastic mesh filter in my combo ac/heat unit. They are quite thin, easily installed, no bulk to impact airflow or closing the cover. They cut like a dream for custom fit. As to air quality, well they’re thin and porous so they’re not going to get small dust particles, but getting larger ones, cat hairs, etc., I think they’re worth helping even a little with air quality.

good item larger then expected, cut down to my size works great

Very good price. Work fine.

Piece is big enogh for most all air conditioners. Use scissors to cut to proper size.
