See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand—made for Lakemont families and mineral-rich central Florida water.
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, with a UV chamber inline. With no bulky storage tank, you get purified water on demand—great for Lakemont’s humid subtropical lifestyle and busy kitchens.
The first cartridge catches rust, dirt, sand, and larger particles before anything downstream sees them.
Carbon block media that reduces chlorine, odors, color, and chemicals before the membrane—ideal for mineral-rich Lakemont water.
The heart of the system, rejecting dissolved solids and heavy metals—helpful with mineral-rich Floridan Aquifer water common in central Florida.
The final cartridge polishes the water and adds beneficial minerals back for a balanced pH—perfect for Lakemont homes.
Filtration Stages
Each stage handles what the one before it left behind—helpful with Lakemont’s mineral-rich groundwater. 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.
Removes rust, dirt, sand, and large particles—helpful with mineral-rich Florida groundwater.

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 Lakemont homes dealing with mineral-rich, hard water from the Floridan Aquifer. 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.
