A small portable appliance for purifying potable water. A vertical “C”shaped body supports a purified water container on its lower horizontal leg. The rearward portion of the body\s vertical back releasably carries a filtration cartridge defining three separate intercommunicating chambers replaceably carrying a pre-filter cartridge, an osmotic filter cartridge and a carbon post-filter cartridge. Control circuitry shuts off water input when the purified water container is full, senses and annunciates the amount of dissolved solids in effluent water and measures use time to annunciate estimated time for filter cartridge change. Internal structure provides storage for a removable connector tube.

A portable self-contained purifying appliance for potable water comprising, in combination: a body having an elongate horizontal lower arm for support on a supporting surface with a vertical portion extending upwardly from one end thereof to support an upper arm extending perpendicularly to the upright and over the lower arm at a spaced distance thereabove, said body having means in the lower arm to carry a container support, a chamber defined in the upright portion to releasably receive a purification cartridge, and water input means to input water to a purification cartridge, including solenoid valve means to regulate the flow of input water; a container support carrying a water container, said support having a medial depending support cylinder slidably carried for vertical motion within a channel defined in the lower arm, said container support being biased to an upper position and having a three position sensitive switch to sense the conditions of no container being supported, an unfilled container being supported, and a filled container being supported; a purification cartridge releasably carried within the purification cartridge chamber defined in the body upright, said purification cartridge defining three adjacent, sequentially intercommunicating chambers, the said first chamber carrying a mechanical filter and a particulated carbon filter, the second chamber carrying an osmotic filter and the third chamber carrying a particulated carbon filter, and having means to pass water from the third cylinder to the container carried by the body structure; and means of removing saline water from the unfiltered side of the osmotic filter carried in said second chamber; and associated electrical control circuitry to open the solenoid valve of the water input means only when a water container be in supported position on the container support and be not full, timing circuitry to determine the lapse of time of operation of the solenoid valve of the water input means and annunciate passage of a predetermined time, and circuitry to sense and annunciate the electric resistivity of water in the appliance to determine operational efficiency of the device.
