See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand for your North Miami Beach home.
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 storage tank—so you get purified water on demand, not sitting in a tank in our warm, humid climate.
The first cartridge catches rust, dirt, sand, and larger particles—helpful with Miami-Dade’s hard-water scale issues.
Carbon block media that reduces chlorine, odors, colors, and chemicals before the membrane—great for local tap water.
The heart of the system—rejects dissolved solids and heavy metals and sends the concentrate to the drain.
The final cartridge polishes the water and adds beneficial minerals back for a balanced pH.
Filtration Stages
Each stage handles what the one before it leaves behind—ideal for Miami-Dade’s hard, limestone-influenced water. UV is the fourth step and the one stage that is not filtration at all; it’s there to handle what filters can’t catch.
Removes rust, dirt, sand, and large particles—before they reach your glass.
Helps reduce chlorine, odors, colors, and chemicals in North Miami Beach tap water.
Removes up to 99% of dissolved solids, heavy metals, and more—helpful with Miami-area hard water from limestone aquifers.
Kills 99.99% of bacteria, viruses and microorganisms.
Adds beneficial minerals for a balanced, healthy pH.
Four filtration stages plus UV sterilization. Steps 1–3 and 5 are filtration; step 4 is the built-in UV lamp (disinfection). It’s included in the price on every system we install in North Miami Beach.

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—great for Miami-Dade homes dealing with hard, limestone-aquifer water and scale. 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.
