See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand—perfect for Bay Harbor Islands families.
The System Itself
Designed to fit neatly under your sink with quick-connect fittings. Four quick-change twist cartridges handle the filtration stages, with a UV chamber inline. No bulky storage tank—so you get purified water on demand, ideal for Bay Harbor Islands kitchens.
The first cartridge catches rust, dirt, sand, and larger particles before anything downstream sees them.
Carbon block media that reduces chlorine, odors, color, and chemicals before the membrane—helpful with Miami-Dade municipal water.
The heart of the system—rejecting dissolved solids and heavy metals and sending 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 something the one before it left behind. UV is the fourth step in the sequence and the one stage that is not filtration at all—it’s there to help protect your drinking water after treatment.
Removes rust, dirt, sand, and large particles—before they reach your glass.
Reduces chlorine, odors, color, and chemicals from Miami-Dade tap water.
Removes up to 99% of dissolved solids, heavy metals, and more—helpful with hard Miami-Dade water.
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 the filtration stages; step 4 is the built-in UV lamp for disinfection (not filtration). It’s included in the price on every system we install in Bay Harbor Islands.

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 Bay Harbor Islands kitchens. 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.
