See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand—perfect for Lake Cain Hills’ humid subtropical Central Florida lifestyle.
The System Itself
The whole system fits under your sink and connects with quick-connect fittings. Four quick-change twist cartridges handle the four filtration stages, and a UV chamber sits inline between them. There’s no bulky storage tank, so Lake Cain Hills families get purified water on demand.
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—great for Central Florida tap 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—ideal for Lake Cain Hills.
Filtration Stages
Each stage handles something the one before it left behind. 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, for added peace of mind in Lake Cain Hills.

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 Cain Hills homes. 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.
