See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand—great for Orangetree families dealing with hard groundwater and mineral scale.
The System Itself
Designed for Orangetree homes, the whole system fits under your sink and connects with quick-connect fittings. Four quick-change twist cartridges handle the filtration stages, with a UV chamber inline. No bulky storage tank—water is purified on demand instead of sitting and waiting.
The first cartridge traps rust, dirt, sand, and sediment—great for Southwest Florida groundwater before it reaches later stages.
Carbon block media that reduces chlorine, odors, color, and chemicals before the membrane—helpful with Southwest Florida water.
The heart of the system—rejecting dissolved solids and heavy metals and sending the concentrate to the drain, even with hard Southwest Florida groundwater.
The final cartridge polishes the water and adds beneficial minerals back for a balanced pH—great for Orangetree households.
Filtration Stages
Each stage handles what the one before it left behind—helpful for Southwest Florida water that can leave mineral scale behind. UV is the fourth step, and it’s not filtration at all; it’s there to handle what filters can’t catch.
Removes rust, dirt, sand, and large particles—great for Southwest Florida groundwater.
Reduces chlorine, odors, color, and chemicals for cleaner-tasting water in Orangetree.

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 Orangetree homes dealing with mineral scaling from hard 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.
