See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand—perfect for Osceola County’s humid, active lifestyle.
The System Itself
Designed to fit under your sink with quick-connect fittings. Four quick-change twist cartridges handle the filtration stages, with a UV chamber inline. No bulky storage tank—just purified water on demand for Osceola County homes.
The first cartridge—catching rust, dirt, sand, and larger particles before they reach the rest of your system.
Carbon block media that reduces chlorine, odors, colors and chemicals before the membrane—helpful with Osceola’s mineral-rich water.
The heart of the system—rejecting dissolved solids and heavy metals, especially important with mineral-rich Floridan aquifer water.
The final cartridge polishes the water and adds beneficial minerals back for a balanced pH—great for Osceola County households.
Filtration Stages
Each stage handles what the one before it left behind—great for Osceola County’s mineral-rich, hard water from the Floridan aquifer. UV is the fourth step in the sequence, and the one stage that is not filtration at all—it is there to deal with what a filter cannot 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—ideal for Osceola County homes on mineral-rich Floridan aquifer groundwater. 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.
