See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand for your Port Mayaca family.
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, and a UV chamber sits inline. There’s no bulky storage tank, so water is purified on demand—great for Port Mayaca’s humid subtropical climate.
The first cartridge catches rust, dirt, sand, and larger particles before anything downstream sees them.
Carbon block media that reduces chlorine plus the taste/odor issues that can show up near the Okeechobee Waterway—before the membrane.
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.
Filtration Stages
Each stage handles what the one before it left behind. UV is the fourth step, and it is not filtration at all—it helps address what filters cannot, especially when Lake Okeechobee and the Okeechobee Waterway influence seasonal taste/odor here.
Removes rust, dirt, sand, and large particles.
Reduces chlorine and common taste/odor issues.
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 for disinfection—helpful when source water conditions around Lake Okeechobee shift seasonally. It’s included in the price on every system we install.

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—great for Port Mayaca homes where water conditions can be influenced by Lake Okeechobee and the Okeechobee Waterway. 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.
