See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand for your Saint Joe home.
The System Itself
The whole system fits under your sink and connects with quick-connect fittings. Four quick-change twist cartridges provide four filtration stages, with a UV chamber inline. No bulky storage tank—so you get purified water on demand, not sitting in humid Gulf County air.
The first cartridge catches rust, dirt, sand, and larger particles—great for Saint Joe water that can vary by source.
Carbon block media that reduces chlorine, odors, colors and chemicals before the membrane—great for municipal water in Port St. Joe.
The heart of the system—rejecting dissolved solids and heavy metals, then sending the concentrate to the drain (ideal when source water varies between city and well).
The final cartridge polishes the water and adds beneficial minerals back for a balanced pH—great for everyday drinking in Saint Joe.
Filtration Stages
Each stage handles what 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’s there to address what a filter can’t catch, especially when water quality varies between in-town municipal lines and nearby private wells.
Removes rust, dirt, sand, and large particles—helpful for city or well water around Saint Joe.

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 Saint Joe’s humid, coastal conditions. 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—great whether you’re on municipal water in town or a private well outside Saint Joe.
