I installed the filter 2 weeks ago, time will tell if it is superior to other filters I have purchased. I can tell you, the filter fit correctly and seems just as sturdy as other filters.My only issue is with the company, not the product. Filterbuy stresses their products are made in America, yet they don't offer a veterans discount.
Nice filters nice prices, QA, not so much. The first filter of the 6 I purchased was slightly miss manufactured or defective, I had to break a glue joint and move the paper to eliminate a hole or open area where the filter meets the cardboard frame.
