Hard to find filter

Your review: I have an older furnace that requires a 2x20x25; often I used 2 filters at 1x20x25- one premium and one sub-standard to fill the space. This one filter fits perfectly and does a much better job at filtering than my former concoction. I'm glad I did a little more research and found this filter. The price was reasonable too.
