Very happy with the quality, service and timely manner. Price can’t be beat. I’ll never go back to the old way of buying filters

Smaller than standard filter.

The filters that I’ve used for the last 10 years measure 23 7/8 square and fit snuggly into the return air receiver. Your filters measure 23 3/8 square and barely cover the edges of the receiver allowing blow by around the edges. I had to tape them in to keep this from occurring. Not pleased with the product at all for this reason. I don’t believe I’ll purchase anymore regardless of the filter quality which I don’t know yet. I changed them quarterly and my ducts are super clean after 10 years and I want to keep them that way. I liked the price, but I guess I found out that you get what you pay for. Disappointed!

This is very comparable to the name brand filter as far as the construction and appearance goes and lasts for a couple months without showing any signs of deterioration.

Actual Size

After many years purchasing the same box of filters I got just what I asked for - 24X30. Somehow I missed the small print: 24x30 (actually 23 1/2 x 29 1/2).
My fault. This company has been great to deal with, and I highly recommend them on quality and value
