See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand for Hobe Sound families.
The System Itself
Designed for Hobe Sound homes, the system fits under your sink and connects with quick-connect fittings. Four quick-change twist cartridges handle the four filtration stages, with a UV chamber inline. No bulky storage tank—water is purified on demand instead of sitting and waiting.
The first cartridge captures rust, dirt, sand, and larger particles—helpful for local well and municipal water before it reaches anything downstream.
Carbon block media that reduces chlorine, odors, colors, and chemicals before the membrane—great for Martin County water.
The heart of the system, rejecting dissolved solids and heavy metals—ideal for hard well or municipal water in our area.
The final cartridge polishes the water and adds beneficial minerals back for a balanced pH—great for daily drinking.
Filtration Stages
Each stage handles what the one before it left behind—ideal for hard municipal or well water common around Hobe Sound. UV is the fourth step and the only stage that isn’t filtration at all; it handles what filters can’t catch.

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—perfect for Hobe Sound homes dealing with hard municipal or 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.
