The filters came more quickly

The filters came more quickly than I expected and I appreciate the quality of the Merv 13 filters. I have 3 cats and 4 adults in my house so we generate a lot of hair and dust. This filter helps a lot! The price isn't too bad for 4 filters. Changing them out once every 3 months instead of every month is a blessing. I just set the reminder on my calendar. I just wish I could get all of the features the Merv 13 features along with the odor control but alas! You cannot have everything I suppose lol!

Awesome Filter and Recommendation!!!

The 20x23x1 filter fit is perfect. I was using the wrong size, per Tony (AC Tech). Tony(AC Tech) told me the filter size for the AC unit was wrong. The 20x22x1 filter I had inside the AC unit was wrong as well. He told me the right AC filter is 20x23x1 and gave me some tips for maintaining my AC unit as well. I would love for him to come back and give me more unit service tips as a user. In the meantime, I went out and purchased a basic AC service manual. . . . KUDOS to Tony!!!!!!

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!
