See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand—built for Winding Cypress living in Collier County’s humid climate.
The System Itself
The whole system fits under your sink and connects with quick-connect fittings—great for Winding Cypress homes. Four quick-change twist cartridges handle the filtration stages, and a UV chamber sits inline between them. There’s no bulky storage tank, so water is purified on demand instead of sitting and waiting.
The first cartridge catches rust, dirt, sand, and particles—helpful with hard-water sediment common around Winding Cypress.
Carbon block media that reduces chlorine, odors, color, and chemicals—helpful with hard water common around Winding Cypress.
The heart of the system—rejects dissolved solids and heavy metals and sends the concentrate to the drain.
The final cartridge polishes the water and adds beneficial minerals back for a balanced pH—great for hard water in Winding Cypress.
Filtration Stages
Each stage handles what the one before it left behind. UV is the fourth step in the sequence—and the one stage that is not filtration at all. It’s there to address what a filter can’t catch.
Removes rust, dirt, sand, and large particles—great for hard-water areas like Winding Cypress.
Reduces chlorine, odors, colors, and chemicals for cleaner-tasting water in Winding Cypress.

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 Winding Cypress homes in Collier County where hard water is common. 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.
