See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand for San Blas homes—ready whenever your family is.
The System—Installed in San Blas
The whole system fits under your sink and connects with quick-connect fittings. 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 your San Blas water is purified on demand rather than sitting and waiting.
The first cartridge catches rust, dirt, sand, and large particles—before anything downstream sees them.
Carbon block media that takes out chlorine, odors, colors, and chemicals ahead of the membrane.
The heart of the system—rejecting dissolved solids and heavy metals and sending the concentrate to the drain for cleaner water in your San Blas kitchen.
The final cartridge polishes the water and adds beneficial minerals back for a balanced pH—perfect for everyday drinking in San Blas.
Filtration Stages
Each stage handles what the one before it left behind. UV is the fourth step in the sequence and the one stage that is not filtration at all - it is there to deal with what a filter cannot catch for San Blas homes.
Removes rust, dirt, sand, and large particles common in tap 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 San Blas sink with quick-connect fittings. 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.
