The site has all the filters sizes and Merv selection that our facility needs. So, it makes it very easy to order and stock only what we need. Thank you, Randy,
All is can tell you about the filter is it fit my a/c unit. I did not install it immediately. It was about a week. I think Iwould need to use it a month or so to determine how good it works. You have any questions.
This filter fits the area perfect easily installed and removed. I write installed date and change it every three months. Catches a lot of dust. House air feels cleaner.
