摘要

Swimming bath water filter has filter particles (15) which are supported by a sieve (14) made up of components with a rhombic, oval or circular longitudinal cross-section and circular transverse cross-section. These have slits (18) in their surface and supporting tubes (16, 17) which have water inlets and outlets (19, 20).
