If you need a replacement filter for your B&D 4-cup thermal coffee maker (or a model like DCM 20 WH), you can often use a universal paper basket filter — check the size (diameter/height) of the original filter basket. Many standard #4 (or similar) filters will fit. If you want exact match or specs, check the user manual for guidance:
