Usually make one annual order for my yearly supply of AC filter replacements (for several years now). My system requires three different sizes, two that are standard and one that is a special order. As a matter of fact, it was the special size that initiated my first dealings with Filterbuy. Have always been satisfied with the pricing, convenience and timeliness in which the orders have been processed. Very happy with the product and the process.
I was disappointed in the quality. I bought these because the price was good but when I received them I was disappointed. The pleats are not uniform. I hope they still work because I ordered three for each unit that I have. I will not buy these again because Im not sure they will work as well as others.
