See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand for your Lake Marian Highlands family.
The System Itself
Designed to fit under your sink with quick-connect fittings—ideal for Lake Marian Highlands homes. Four quick-change twist cartridges provide four filtration stages, with a UV chamber inline. No bulky storage tank, so water is purified on demand instead of sitting and waiting.
The first cartridge catches rust, dirt, and sand—helpful for Osceola County well and groundwater supplies.
Carbon block media that reduces chlorine, odors, and chemicals before the membrane—helpful with Osceola County well water.
The heart of the system—rejecting dissolved solids and heavy metals and sending the concentrate to the drain.
The final cartridge polishes the water and adds beneficial minerals back for a balanced pH—great with hard water common here.
Filtration Stages
Each stage handles what the one before it left behind—helpful for Lake Marian Highlands well water where hardness and iron/sulfur staining can be common. UV is the fourth step in the sequence and the one stage that is not filtration at all—it is there to deal with what a filter cannot catch.
Removes rust, dirt, sand and large particles—common in groundwater and well sources.
Reduces chlorine, odors, colors, and chemicals.
Removes up to 99% of dissolved solids, heavy metals, and more—helpful with hard well water in this area.
Kills 99.99% of bacteria, viruses and microorganisms.
Adds beneficial minerals for a balanced, healthy pH.
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 (disinfection, not filtration) and it’s included in the price on every system we install in Lake Marian Highlands.

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 Lake Marian Highlands homes on groundwater and well sources. 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.
