Arrived very quickly, was more affordable than other offers I found, and fit perfectly.

It's the filter my machine uses, but what I like best is that it's so much less expensive to go through Discount Filters than the company which sold and installed the HVAC system. DF also has lovely representatives, patient, friendly and the product is shipped very quickly.
