See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand for your Riomar home and family.
The System Itself
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. There’s no bulky storage tank—so in Riomar’s humid subtropical climate, water is purified on demand instead of sitting and waiting.
The first cartridge catches rust, dirt, sand, and larger particles—helpful with Jacksonville-area mineral content.
Carbon block media that reduces chlorine, odors, colors, and chemicals before the membrane—great for Jacksonville-area water.
The heart of the system—rejecting dissolved solids and heavy metals and sending the concentrate to the drain, helping combat scale from moderate mineral content in the Jacksonville area.
The final cartridge polishes the water and adds beneficial minerals back for a balanced pH—great for everyday drinking in Riomar.
Filtration Stages
Each stage handles what the one before it left behind—helpful in the Jacksonville area, where moderate mineral content can contribute to scale buildup. UV is the fourth step and the one stage that is not filtration at all; it targets what a filter can’t catch.
Removes rust, dirt, sand, and large particles—helpful with mineral-related scale.
Removes chlorine, odors, colors, and chemicals common in Jacksonville-area tap water.
Removes up to 99% of dissolved solids, heavy metals and more—great for Riomar’s moderate mineral content.
Kills 99.99% of bacteria, viruses and microorganisms.
Adds beneficial minerals for a balanced, healthy pH—ideal for Riomar drinking water.
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. With Jacksonville-area summer heat and humidity that can accelerate biofilm growth, UV adds an extra layer of protection—and it’s included in the price on every system we install.

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 Riomar homes in the Jacksonville metro area. 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, helping reduce the mineral content that can contribute to scale buildup in Jacksonville-area plumbing. It sends 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—especially helpful in our humid subtropical climate, where summer heat and humidity can accelerate biofilm growth in plumbing and filtration systems—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.
