Furnace Filters
OK I need some help from the brain trust. My furnace filter is one of the washable - reusable types that was in the furnace when we moved in 12 years ago. I wash it out regularly and it catches a lot of crud but I want something better. I know how to use a tape measure. That filter is 20.5 x 30 inches plus or minus a 32nd of an inch. There are lots 20 x 30 filters on the market. I can't find anything that is 20.5 x 30.
What am I missing? Will a 20 x 30 filter work with a 1/4 inch gap on each side?
