WORKS WONDERS on my review.

The style is a bit different from the last time I ordered them but this is about 8 months of buildup vs brand new. I should have definitely changed it sooner but it’s crazy how much these filter out of our air. (Our a/c is only 2 years old and we live in Florida.) It blows my mind thinking of using a 1” filter vs this 4 3/8” filter in all other homes I’ve lived in. Yikes! I highly recommend these. Cheapest ones I’ve found online, last a long while and filter out a ton.

Pros

it is all good

Cons

Inadequate sizing: While the product dimensions claim to fit Rheem, Ruud, and Protech furnace units, the actual size is slightly smaller than advertised, making it difficult to install properly and reducing its overall effectiveness
