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—built for the Orange County (Orlando metro) lifestyle.
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 you get purified water on demand—ideal for busy Sky Lake kitchens.
The first cartridge catches rust, dirt, sand, and larger particles—helpful with mineral scale common in Central Florida.
Carbon block media that reduces chlorine, odors, colors, and chemicals before the membrane—great for Orange County tap water.
The heart of the system, rejecting dissolved solids and heavy metals and sending the concentrate to the drain—helpful with Central Florida hard water.
The final cartridge polishes the water and adds beneficial minerals back for a balanced pH—great for Sky Lake families.
Filtration Stages
Each stage handles what the one before it leaves behind—especially helpful for Orange County homes dealing with hard-water mineral scale. UV is the fourth step, and it’s not filtration at all; it’s there to address what filters can’t catch.
Removes rust, dirt, sand, and large particles—great for Central Florida homes.
Reduces chlorine, odors, colors, and chemicals.
Removes up to 99% of dissolved solids, heavy metals, and more—helping reduce minerals in Central Florida hard 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—great for Sky Lake homes dealing with Central Florida hard-water scale. 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.
