Apparatus for water filtration, ozone, and ultraviolet disinfection
A filtration system that includes a coarse filter, a fine filter, and a pump. The coarse filter filters out sediment from water passing through the coarse filter. The fine filter filters out foreign material larger than a selected pore size. The pump pumps water when a DC voltage is applied to the fluid pump. The pump is in-line with and coupled to the coarse filter and the fine filter such that water is drawn into or pushed into the coarse filter and/or the fine filter. The filtration system includes inlet and outlet connectors, the inlet connector directly coupled to the coarse filter to receive water into the coarse filter and the outlet connector directly coupled to the fine filter to output filtered water received from the fine filter. A power source is coupled to the fluid pump and outputs the DC voltage applied to the fluid pump.
