See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand—built for Williston Highlands hard well water and busy family life.
The System Itself
The whole system fits under your sink and connects with quick-connect fittings. Four quick-change twist cartridges carry the four filtration stages, and a UV chamber sits inline between them. There is no bulky storage tank, so the water is purified on demand—great for Williston Highlands homes on private wells.
The first cartridge catches rust, dirt, sand, and larger particles—especially helpful for Williston Highlands well water.
Carbon block media that reduces chlorine, odors, colors, and chemicals before the membrane—ideal for Levy County water sources.
The heart of the system—rejecting dissolved solids and heavy metals often found in mineral-rich Florida aquifer well water.
The final cartridge polishes the water and adds beneficial minerals back for a balanced pH—without the harsh taste.
Filtration Stages
Each stage handles what the one before it leaves behind—ideal for Williston Highlands homes on private wells. UV is the fourth step and the one stage that is not filtration at all; it helps address what filters 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 Williston Highlands homes on private wells. 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.
