See the purity, trust the technology. A tankless under-sink system delivering ultra-clean, refreshing water on demand—ideal for Everglades homes dealing with hard, mineral-rich water.
The System, Up Close
Designed for Everglades-area homes, the whole system fits under your sink and connects with quick-connect fittings. Four quick-change twist cartridges provide the filtration stages, with a UV chamber inline. There’s no bulky storage tank, so water is purified on demand instead of sitting in a tank.
The first cartridge captures rust, dirt, sand, and grit before it reaches the rest—helpful after storms and flooding.
Carbon block media that reduces chlorine, odors, colors, and chemicals before the membrane.
The heart of the system—helps reduce dissolved solids and heavy metals, sending the concentrate to the drain.
The final cartridge polishes the water and adds beneficial minerals back for a balanced pH—great for hard, mineral-rich South Florida water.
Filtration Stages
Each stage handles what the one before it left behind—helpful for hard, mineral-rich water common across South Florida. UV is the fourth step and the one stage that isn’t filtration at all; it’s there to handle what a filter can’t catch.
Removes rust, dirt, sand, and larger particles—great for storm-prone areas.
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 back for a balanced, healthy pH.
Four filtration stages plus UV sterilization. Steps 1–3 and 5 are the filtration stages; step 4 is the built-in UV lamp for disinfection. It’s included in the price on every system we install across the Everglades/Collier County area.

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—built for Everglades-area conditions where hard, mineral-rich water and storm-driven sediment can be a concern. 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.
