Abstract: The specification relates to a filter candle for filtering highly-viscous fluids, e.g. polymer melts, and in a number of parts which can be dismantled and comprising a filter stocking permanently connected to a cap, the two parts being replaceable together. Owing to the complete absence of screwed components, the filter candle can be made very small. It is also easier to take apart and clean when clogged by solidified residues of melt. Individual parts can easily be replaced when unserviceable. The complete filter candle has a plug connection to a baseplate, from which it can rapidly be separated.
