See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand for your Yamato home.
The System
The whole system fits under your sink and connects with quick-connect fittings. Four quick-change twist cartridges provide the four filtration stages, with a UV chamber inline. No bulky storage tank—so you get purified water on demand, without it sitting and waiting in Yamato’s heat and humidity.
The first cartridge catches rust, dirt, sand, and larger particles—helpful with Yamato’s hard municipal water.
Carbon block media that reduces chlorine, odors, color, and chemicals before the membrane—ideal for Yamato tap water.
The heart of the system, rejecting dissolved solids and heavy metals and sending the concentrate to the drain—helpful with Yamato’s hard water.
The final cartridge polishes the water and adds beneficial minerals back for a balanced pH—great for Yamato homes.
Filtration Stages
Each stage handles what the one before it left behind—ideal for Palm Beach County homes dealing with hard municipal water. UV is the fourth step and the one stage that is not filtration at all; it targets what a filter cannot catch.
Removes rust, dirt, sand, and large particles—before they can build up in your plumbing.
Reduces chlorine, odors, color, and chemicals.
Removes up to 99% of dissolved solids, heavy metals, and more—great for Yamato’s hard municipal 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 Yamato homes dealing with hard municipal water and scale buildup. 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.
