SwissGold Coffee Filter, KF-4 Universal Cone SwissGold 23 carat gold-plated coffee filters Permanent filter replaces paper filters Durable, easy to clean, and top-rack dishwasher safe KF 4 cone filter fits 8-12 cup cone shape filter coffee makers, replacing 4 paper filters SwissGold 23 carat gold-plated coffee filters are permanent, created to replace paper filters. They are reusable time and again, so youll never again worry about running out of filters. In addition to filtering coffee grinds, paper filters can also filter out coffee's essences, aromas, and flavor - and even add a slight paper flavor of their own. SwissGold permanent coffee filters allow only the true, full flavor of your coffee into your pot. Theyre durable, easy to clean, and top-rack dishwasher safe. KF 4 cone filter fits 8-12 cup cone shape filter coffee makers, replacing 4 paper filters. The difference in taste between these and paper filters is unimaginable. It's not the same as French pressed coffee: not as thick mouthfeel, brighter. The SwissGold filter is fine enough that there is very little sediment, a problem cheaper knock-offs suffer badly from. The filter has an indented rim to let you pick it up, rather than a handle. One thing the write-up doesn't mention is that there is an extension ring hiding in the box under the little cardboard bit the filters sits in.
