See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand for Bay Lake families in the Walt Disney World area.
The System Itself
The whole system fits under your sink and connects with quick-connect fittings—perfect for Bay Lake kitchens. Four quick-change twist cartridges carry the four filtration stages, and a UV chamber sits inline between them. There is no bulky storage tank, so the water is purified on demand rather than sitting and waiting.
The first cartridge catches rust, dirt, sand, and larger particles before anything downstream sees them—helpful with utility-supplied water in the area.
Carbon block media that reduces chlorine, odors, colors, and chemicals before the membrane—ideal for utility water in the Bay Lake area.
The heart of the system, rejecting dissolved solids and heavy metals and sending the concentrate to the drain—great for Bay Lake utility water.
The final cartridge polishes the water and adds beneficial minerals back for a balanced pH—ideal for Bay Lake drinking water.
Filtration Stages
Each stage handles what the one before it left behind. For Bay Lake’s utility-supplied water in the Walt Disney World area, UV is step four—and it’s not filtration at all. It’s there to address 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—ideal for Bay Lake homes on municipal/utility-supplied 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.
