Great Filter

I have been using Filterbuy filters for numerous years and change them out regularly. I have always been pleased with just how good of a filter they are compared to other filters that do not even compare in quality. The price is very reasonable so that is why I always purchase 12 filters at a time and I received them within 2 days of ordering. I will continue using Filterbuy so I do not have to worry about my filters being great!

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.
