washable central H & A filters?
I'm looking for imput on different types of washable filters. I have read the H & A forum, but didn't see anything about washable ones, except possibly one person who uses cheap filters and a black overlay of window filter.
I usually vacuum my filter weekly. I probably only wash every 6 mos. I alternate 2. How long should the washable type last? How clean am I getting it, running water from the backside through it? I don't remember the filter co. recommending using soap. I have had these for a while.
Basically - what do you use?
