ABSTRACT:
A water purification system utilizes a radial filter and an ultraviolet lamp in a small, portable, countertop housing. A standpipe is positioned between the filter and the ultraviolet lamp to control the flow of water so that it flows along substantially the entire length of the UV lamp. The lamp is made integral with a quartz-tube covering and a threaded cap and connector to enable replacement of the UV lamp assembly. The housing encompassing the filter system is also easily disassembled to enable cleaning of the housing and replacement of the filter. A pressure vent is provided in the housing cover to equalize pressure and provide for a water level differential when the filter is disabled. A UV lamp indicator is included to show that the lamp is in operation.
