See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand—built for Pennsuco living in a hot, humid climate.
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 water is purified on demand—great for Pennsuco’s hot, humid climate.
The first cartridge catches rust, dirt, sand, and large particles—helpful with Miami-Dade’s groundwater supply.
Carbon block media that reduces chlorine, odors, colors, and chemicals before the membrane—ideal for Miami-Dade’s groundwater supply.
The heart of the system—rejecting dissolved solids and heavy metals often found in hard groundwater and sending the concentrate to the drain.
The final cartridge polishes the water and adds beneficial minerals back for a balanced pH—nice for Miami-Dade’s hard water.
Filtration Stages
Each stage handles what the one before it left behind—especially helpful with Miami-Dade’s typically hard, groundwater-based supply. UV is the fourth step in the sequence and the one stage that is not filtration at all; it’s there to deal with what a filter cannot catch.
Removes rust, dirt, sand, and large particles common in Miami-Dade groundwater supplies.
Removes chlorine, odors, colors, and chemicals common in Miami-Dade tap water.
Removes up to 99% of dissolved solids, heavy metals, and more—great for hard Miami-Dade groundwater.
Kills 99.99% of bacteria, viruses and microorganisms.
Adds beneficial minerals for a balanced, healthy pH—helpful with Miami-Dade’s hard 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, which is not filtration but disinfection—especially valuable in Miami-Dade during hurricane season—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 Miami-Dade’s typically hard, groundwater-based supply. 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.
