Great Product! Most important was the help your customer service gal provided on my 800 phone call to your offices. Her enthusiasm and attitude was the finishing touch. I work at one of the big box stores as retired person and have recommended your 800 line to other seniors. Important to me was to be able to talk with a knowledgeable person eager to help.. thank you all. Bobd in Ohio.

This filter was recommended by the company that cleaned the ducts in my house. This filter is expensive but I think it's worth it.

I'm giving this filter a 5 star rating although I haven't used it in my A/C system. Because it is undercut by 1/2", which would leave that area of my a-coil exposed, I will not be able to use it. My rating is based on price, value, and quality. The filter, in my opinion, is very well made. Had it not been undercut it would have been the filter I've been searching for to replace the crappy overpriced a-coil filters at $16 a pop.
