Best filter I tried.
It was great!, Quick shipment, like the quality and also like the extra comments that were sent about maintenance of the different A/C units we have. This is a company that seems to care about their customers.

First time using this brand.
First time using this brand. I have been in the natural gas business with a service department for 44 yrs. Now retired. I will see how they hold up in my own house. Thank you for your inquiry.
