See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand for your Sun Valley family.
The System Itself
The whole system fits under your sink and connects with quick-connect fittings. Four quick-change twist cartridges handle the four filtration stages, with a UV chamber inline. No bulky storage tank—so you get purified water on demand, a smart fit for Sun Valley’s warm, humid climate.
First cartridge traps rust, dirt, sand, and storm-stirred sediment before anything downstream sees it.
Carbon block media that reduces chlorine, odors, color, and chemicals before the membrane—helpful after Sun Valley’s heavy rains.
The heart of the system—rejecting dissolved solids and heavy metals and sending the concentrate to the drain for cleaner Sun Valley drinking water.
The final cartridge polishes the water and adds beneficial minerals back for a balanced pH—ideal for Sun Valley kitchens.
Filtration Stages
Each stage handles something the one before it left behind. Here in Sun Valley, heavy rains can stir up sediment and organic matter—UV is the fourth step and the one stage that is not filtration at all; it’s there to deal with what a filter cannot catch.

The Mr. Pure Water Under-Sink Reverse Osmosis System with UV Sterilization is a tankless point-of-use system that fits neatly under your sink with quick-connect fittings—ideal for Sun Valley’s warm, humid climate and the heavy rains that can stir up sediment after storms. Cold water enters a PP sediment cartridge that catches rust, dirt, sand and large particles, then a CTO carbon block that takes out chlorine, odors, colors and chemicals. The reverse osmosis membrane removes up to 99% of dissolved solids and heavy metals, sending the concentrate to the drain at a 1.5:1 pure-to-drain ratio. A built-in UV lamp then kills 99.99% of bacteria, viruses and microorganisms - the one thing a filter cannot catch - operating automatically on water flow pressure. An alkaline and mineral stage finishes the water, putting beneficial minerals back for a balanced pH. Five stages in all - PP, CTO, RO, UV and alkaline - producing up to 400 gallons a day on demand, with no bulky storage tank to hold water, take up space or invite secondary contamination.
