To early to tell
on September 12, 2026

Just received the filters. Best part is they actually fit properly. My 20x30 opening was 19 7/8”x 29 7/8”. Sam’s filters were actual size and had to be bent to fit, which damaged the sealing edge. My 3 ton unit really moves some air and bows the filter pretty good. But, time will tell. Bought the six pack to start with. We’ll see in 6 months if I buy again.

Filter does not fit
on September 10, 2026
Posted by: Customer
This was a custom filter and the size of the old one was 24c24 x1. The new ones I received was not correct it should have been 24x20x1. Now I have these filters that are. It even 24 wide that does not enter the opening of the air handler. I order for my other home and never had any issues but not sure why for my mom’s house this is an issue. I hope maybe we could get them replace.
