See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand for your Winter Springs 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, and a UV chamber sits inline between them. There’s no bulky storage tank, so water is purified on demand—perfect for busy Winter Springs kitchens.
The first cartridge catches rust, dirt, sand, and sediment—helpful with mineral-rich groundwater common around Winter Springs.
Carbon block media that removes chlorine, odors, colors, and chemicals before the membrane—ideal for local groundwater supplies.
The heart of the system—rejecting dissolved solids and heavy metals, helping fight hard-water minerals common in Winter Springs.
The final cartridge polishes the water and adds beneficial minerals back for a balanced pH—great for Winter Springs homes.
Filtration Stages
Each stage handles what the one before it left behind. In Winter Springs, where mineral-rich groundwater can mean hard-water scale, UV is the fourth step—and the one stage that isn’t filtration at all. It’s there to handle what a filter can’t 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 Winter Springs homes dealing with hard, mineral-rich groundwater. 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.
