Inquiry (采购产品): old bath filter required 1985 house has two bath fans, both use "D-Mark" with no part number on them. They are metal-covered, 7 1/2 x 6 1/2 filters with a hole in the center for mounting. Can you tell me where I can get replacements for them, and a part number to look for? I've never been able to find them anywhere. If you have dealers in the Dallas area, that would be great, too.
