See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand—great for Florida City families dealing with Miami-Dade hard water and year-round spotting.
The System Itself
The whole system fits under your sink and connects with quick-connect fittings. Four quick-change twist cartridges handle the stages, with a UV chamber inline. No bulky tank—so in Florida City’s warm climate, you get purified water on demand instead of stored water sitting.
The first cartridge catches rust, dirt, and sand—helpful with Miami-Dade’s hard water before it reaches the next stages.
Carbon block media that reduces chlorine, odors, colors, and chemicals before the membrane—ideal for Miami-Dade water.
The heart of the system—rejects dissolved solids and heavy metals, sending the concentrate to the drain (great for hard Miami-Dade water).
The final cartridge polishes the water and adds beneficial minerals back for a balanced pH—perfect for Florida City families.
Filtration Stages
Each stage handles what the one before it left behind—especially helpful with Miami-Dade’s hard water. 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—great for Miami-Dade 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—ideal for Florida City homes dealing with Miami-Dade’s hard water and year-round mineral 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.
