See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand—great for Limestone Creek families in our humid subtropical climate.
The System Itself
The whole system fits under your sink and connects with quick-connect fittings. Four quick-change twist cartridges provide four filtration stages, and a UV chamber sits inline between them. There is no bulky storage tank, so the water is purified on demand—ideal for busy Limestone Creek kitchens.
The first cartridge—catches rust, dirt, sand, and larger particles before anything downstream sees them.
Carbon block media that reduces chlorine, odors, colors, and chemicals before the membrane—helpful in coastal South Florida water.
The heart of the system, rejecting dissolved solids and heavy metals and sending the concentrate to the drain—great for coastal South Florida concerns.
The final cartridge polishes the water and adds beneficial minerals back for a balanced pH—perfect for Limestone Creek.
Filtration Stages
Each stage handles what the one before it left behind—helpful in Limestone Creek, where mineral scale can be a real nuisance. UV is step four, and it’s not filtration at all; it targets what filters can’t catch.
Removes rust, dirt, sand, and larger particles—helpful for coastal South Florida water.
Reduces chlorine, odors, colors, and chemicals for cleaner-tasting Limestone Creek water.
Removes up to 99% of dissolved solids, heavy metals, and more—helpful for coastal South Florida water quality concerns.
Kills 99.99% of bacteria, viruses, and microorganisms.

Four filtration stages plus UV sterilization. Steps 1 to 3 and 5 are the four filtration stages; step 4 is the built-in UV lamp for disinfection—especially reassuring in coastal South Florida. It is included in the price on every system we install.

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 Limestone Creek’s humid, coastal South Florida conditions where mineral scaling and occasional saltwater intrusion concerns can come up. 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.
