Abstract: A filter candle to separate contaminants from a plastic melt is disclosed. The filter candle has a filter element through which a melt flow is directed to retain contaminants contained in the melt flow, and a supporting body to support the filter element. The supporting body is a hollow body having multiple passages for the melt flow. At least one additional supporting body is on the side of said filter element that faces away from the supporting body. The additional supporting body acts on surface regions of the filter element and/or accommodates them such that the filter element can be backwashable.
