The System Itself
Sized to fit under your sink and connect with quick-connect fittings. Four quick-change twist cartridges handle the filtration stages, with a UV chamber inline. No bulky storage tank—purified water on demand for Clewiston kitchens, not sitting and waiting.

Each stage handles what the one before it left behind—helpful for Clewiston’s hard groundwater and mineral scale. UV is the fourth step in the sequence 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—great for Clewiston homes dealing with hard groundwater and mineral scale. 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.
