Inquiry (采购产品): replacement filter I am wondering if you can help me find a replacement filter for a bath exhaust fan. It is probably 15+yrs old. It is a Nutone and I think model C-305C3NA. The filter in it has D-Mark but no part number. The size is about 4 1/4 in by 7 in by 1/4 in. Any help will be greatly appreciated as the current filter is very old and falling apart.
