I'm looking for a five stage air cleaner fliter material that I can cut to size.?

Question:I have two older type air cleaners that need new filters.The original filters are a five stage filtering system that cannot be bought at any hardware store.

Answers:
You may have to contact an HVAC service company and ask for the part over the counter.
If the filter batting is polyester, try a sewing goods store and look for the quilt batting.
If the filter material is foam, the sewing store will also carry this item.
If the filter is fiberglass, you can only get it from a HVAC source.
