Abstract
A filter housing for a portable spa utilizes a coaxial channel structure at the flow output of the filter housing to separate the water flow from the filter housing. In one embodiment, the water from the filter housing, exiting at the bottom of the housing, is piped by way of a high pressure pump, to the jets in the spa. The water from the filter housing taken at about halfway between the top and bottom of the filter housing is piped, by way of a circulation pump to a heater and a water purifier system back into the spa, preferably to a return aperture in the footwell of the spa. In another embodiment water exiting the filter housing is split into separate flow paths at the bottom of the filter housing, to the jets in the spa and into the circulation loop back into the spa.
