ABSTRACT:
The invention provides a filtration system suited to be coupled in a water transfer circuit with a tub, pool, spa, or the like, and includes a housing or casing within which is provided a filter element through which the water passes during operation. In one preferred embodiment, a heater is provided within the housing. The heater comprises an electrical heating element positioned within the center opening of an annular filter element. A pump and motor can be connected to the housing in a water transfer circuit. A strainer for removing hair, lint, or the like is preferably provided within the circuit upstream from the pump, that is to say, between the inlet of the pump and the spa or tub. The strainer can be located within the filter housing adjacent to and in fluid communication with the filter and between the filter and a removable cover releasably secured to the housing.
