See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand—perfect for Mitchell Lake Estates families.
The System Itself
The whole system fits under your sink and connects with quick-connect fittings. Four quick-change twist cartridges handle the filtration stages, with a UV chamber inline. No bulky storage tank—so you get purified water on demand, a smart fit for humid subtropical Florida living.
The first cartridge traps rust, dirt, sand, and sediment—helpful with Florida’s mineral-rich groundwater in some areas.
Carbon block media that reduces chlorine, odors, colors, and chemicals before the membrane—ideal for Florida 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 for mineral-rich Florida water.
Filtration Stages
Each stage handles what the one before it left behind. UV is the fourth step and the one stage that is not filtration at all—it is there to address what a filter cannot catch.
Removes rust, dirt, sand, and large particles—common with Florida groundwater.
Reduces chlorine, odors, colors, and chemicals.
Removes up to 99% of dissolved solids, heavy metals, and more.
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). It’s included in the price on every system we install in Mitchell Lake Estates.

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 Mitchell Lake Estates homes dealing with mineral-rich Florida groundwater or private well water. 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.
