"I can't use a permanent filter because they are rigid and I have to bend my filter to install it." Problem solved! The ECO-FLEX filter is designed to bend and flex when necessary but is also rigid enough to stay in place. Another benefit...because it does not have a metal frame, it is only 5/8 inch thick. This filter has the same specs as our GOLD frame filter with a polypropylene webbing frame sewn around the edge. We recommend that the flex filters only be used in applications where a metal filter will not fit.
This filter comes in 5/8 inch thickness only.

Because they are flexible, they’re easy to get in and out. My system takes three filters. In less than a year I will have recovered the cost of my permanent filters. I am very happy to have found these.
I am very happy with the ECO-FLEX filter I bought from NeverBuyAnotherFilter.
The website is very easy to use and the delivery was fast. It fit perfectly in my furnace.
