See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand—built for Sunniland’s mineral-rich, hard-water conditions.
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, with a UV chamber inline. No bulky storage tank—so you get purified water on demand, a big plus for Sunniland well-water homes.
The first cartridge traps rust, dirt, and sand—common in rural well water—before anything downstream sees it.
Carbon block media that reduces chlorine, odors, colors, and chemicals before the membrane—ideal for mineral-rich South Florida water.
The heart of the system—rejecting dissolved solids and heavy metals that can come with mineral-rich South Florida groundwater.
The final cartridge polishes the water and adds beneficial minerals back for a balanced pH—great for hard-water areas like Sunniland.
Filtration Stages
Each stage handles what the one before it left behind—ideal for Sunniland’s common well water and mineral-rich groundwater. UV is the fourth step and the one stage that isn’t filtration at all; it targets what a filter can’t catch.
Removes rust, dirt, sand, and large particles—ideal for many Sunniland well systems.

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 Sunniland homes on rural well 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.
