PURPOSE:To obtain a filter unit which allows itself to be easily disassembled and assembled and physically washed by connecting a tubular filter to a connector pipe, supported through an elastic pipe and storing the filter in a casing tube. CONSTITUTION:Either one of connector pipes 4 attached to both ends of casing tube 3 is removed by loosening a union nut 10. Then a tubular filter 2 is attached to a sleeve 11 of the connector pipe 4 through an elastic pipe 5 and is introduced into the casing tube 3. Again the connector pipe 4 and casing tube 3 are tightened by adjusting the union nut 10. Thus a filter unit 1 can be easily set. This filter unit 1 can be back-washed as it is and also physically washed because it is easily disassembled.
