See the purity, trust the technology. A tankless under-sink system delivering ultra-pure, clean, refreshing water on demand for Westchester families across Miami-Dade.
The System Itself
This tankless system fits neatly under your sink with quick-connect fittings. Four quick-change twist cartridges handle the filtration stages, and a UV chamber sits inline. With no bulky storage tank, you get purified water on demand—perfect for busy Westchester kitchens.
The first cartridge catches rust, dirt, and sand before it can move downstream through the system.
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 and sends the concentrate to the drain, helping with Miami-Dade’s hard, limestone-based water.
The final cartridge polishes the water and adds beneficial minerals back for a balanced pH—great for Westchester households.
Filtration Stages
Each stage handles what the one before it left behind. In Miami-Dade’s limestone-based water (Biscayne Aquifer), that layered approach matters. UV is the fourth step and the one stage that is not filtration at all—it handles what filters cannot catch.
Removes rust, dirt, sand and large particles.
Reduces chlorine, odors, colors, and chemicals.
Removes up to 99% of dissolved solids, heavy metals, and more—helpful for Miami-Dade’s hard, limestone-based 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 to 3 and 5 are the four 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 Westchester.

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 Westchester 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.
