See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand for you and your family in Fort Mason.
The System Itself
The whole system fits under your sink and connects with quick-connect fittings. Four quick-change twist cartridges carry the filtration stages, and a UV chamber sits inline between them. There is no bulky storage tank, so the water is purified on demand—ideal for Fort Mason households dealing with hard water.
The first cartridge catches rust, dirt, and sand—helpful with Central Florida’s mineral-rich water before it reaches later stages.
Carbon block media that reduces chlorine, odors, colors and chemicals before the membrane—great for Fort Mason water.
The heart of the system, rejecting dissolved solids and heavy metals and sending the concentrate to the drain—helpful with Central Florida’s higher mineral content.
The final cartridge polishes the water and adds beneficial minerals back for a balanced pH—great for everyday drinking in Fort Mason.
Filtration Stages
Each stage handles what the one before it left behind—especially helpful with the harder water common around Fort Mason. UV is the fourth step and the one stage that isn’t filtration at all; it’s there to deal with what a filter can’t catch.
Removes rust, dirt, sand and large particles—common in mineral-rich Central Florida water.

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 Fort Mason homes dealing with Central Florida’s harder water and scale buildup. 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.
