See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean and refreshing water on demand for you and your family in Yniestra.
The System Itself
The whole system fits under your sink and connects with quick-connect fittings. Four quick-change twist cartridges handle the four filtration stages, and a UV chamber sits inline between them. There’s no bulky storage tank, so your Yniestra water is purified on demand rather than sitting and waiting.
The first cartridge catches rust, dirt, sand, and large particles—so nothing downstream takes the hit.
Carbon block media that takes out chlorine, odors, colors, and chemicals ahead of the membrane—great for Yniestra tap water.
The heart of the system, rejecting dissolved solids and heavy metals and sending the concentrate to the drain.
The final cartridge, polishing the water and adding beneficial minerals back for a balanced pH.
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 isn’t filtration at all. It’s there to deal with what a filter can’t catch in your Yniestra water.
Removes rust, dirt, sand, and large particles from Yniestra water.
Removes chlorine, odors, colors, and chemicals.
Removes up to 99% of dissolved solids, heavy metals and more.
Kills 99.99% of bacteria, viruses, and microorganisms.

Four filtration stages plus UV sterilization. Steps 1 to 3 and 5 are the four filtration stages; step 4 is the built-in UV lamp, which is not filtration but disinfection—it's included in the price on every system we install in Yniestra.

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 Yniestra homes. 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.
