Questionable quality
on May 17, 2026
Posted by: Customer
The 14X14 filters are fine. I question why the 18X24 filters are not marked on the frame with the Merv11 marking? I am not convinced I received the same quality filters I expected.

The best for the price.

I live in Florida with two dogs. . . we all have hay fever, yep even the dogs. So top notch filters are a must, but also don't want to starve air to the a/c air handler, so the MERV 11s are wonderful. Can't recommend them too highly.

Filters for Future Use

Purchased filters from area store but wanted standby filters for eventual change. Will try your brand to compare to make sure my nose is not dripping all of the time in our house. Yours will be used in the next two three month round - then I can be able to tell if it was worth it!

The Air I Breathe

After installing the MERV 11 filter, the air I breathe in is like a crisp, clean wind dancing through the trees.
