ABSTRACT:
A filtration and purification apparatus for use in water lines of both domestic and industrial applications, wherein water must be purified and filtered prior to use--particularly with respect to human consumption thereof. The filter/purifier comprises a housing having an inlet port which discharges into a filter chamber, wherein the incoming water passes through a filter member into an adjacent metering compartment which controls the flow of water both through an outlet port and a communicating purifying chamber, the purifying chamber including a predetermined amount of iodine crystals stored therein. Water enters the purifying chamber from the metering compartment and discharges into a mixing compartment which is interposed between the purifying chamber and the outlet port, and the metering compartment and the outlet port, wherein the iodine-treated water is mixed with the filtered water that passes through a flow-control port disposed between the mixing compartment and the metering compartment, thereby allowing filtered and purified water to pass through the outlet port for use.
