I'm want to upgrade the air filter in my gas forced-air furnace. The
current one measures 24" x 15" x 1". I've been using one of those
"permanent" filters, but I'm going to try a good, disposable filter
and see how that works. 3M Filtrete seems like a popular brand, but
I'd be happy to try something that works as well for a lower cost.
Thanks.
