These are a high quality filter which plays an important part of not having to call out AC companies. I change these out frequently, which I do monthly. Not sure I need to do it so much, but it cannot hurt. Also, the company set us up on automatic shipment, so I don't have to rely on memory or a calendar

First time using your service, and the filters didn't fit. It was way too small. I do not want to be charged for returning them.Bruce Wade
