A number of saftey devices are provided to prevent a user from being electrocuted if water reaches the control unit. In the most protected area within the control unit, a rope heater is provided to warm an air stream being driven by said motor and through said air hose to bubble from the air mat.

A cartridge for a water filter system has a closed housing with only an inlet and an outlet formed in the lower surface thereof. A discharge tube extends from the outlet at the bottom, through the housing, to a position near the top of the housing. There, an elongated sleeve of filter material filters the water leaving the housing. The space between the inlet and the filter sleeve is filled with three different filter materials, most of which is activated charcoal.
