I'm having a difficult time finding one of the sizes of HVAC Filters that I need, so it occurred to me that it might be better to buy a washable filter, rather than constantly needing to find and buy new ones, especially since they seem to be getting more difficult to find. I looked around a little, and found an article by who else but Bob Vila, on the subject. Hopefully I can find one or two (I almost never buy 1 of something that is difficult to find, just in case it goes away permanently) of these, and can just wash them out when needed, rather than buying new ones.
