See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand for your Sherman home—especially helpful with hard, mineral-rich water common across the Florida Panhandle.
The System Itself
The whole system fits under your sink and connects with quick-connect fittings. Four quick-change twist cartridges provide 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 Sherman’s humid subtropical climate and busy kitchens.
The first cartridge catches rust, dirt, sand, and large particles—helpful with mineral-rich Panhandle groundwater.
Carbon block media that reduces chlorine, odors, colors and chemicals before the membrane—great for mineral-rich Panhandle groundwater.
The heart of the system—rejecting dissolved solids and heavy metals and sending the concentrate to the drain (helpful with hard, mineral-rich water common in the Panhandle).
The final cartridge polishes the water and adds beneficial minerals back for a balanced pH—nice for Sherman’s mineral-rich water.
Filtration Stages
Each stage handles what the one before it left behind—especially helpful for mineral-rich groundwater common across the Florida Panhandle. 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 Sherman, Florida homes that often deal with mineral-rich groundwater and hard-water 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.
