See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand for your West Little River family—without the bottled-water runs.
The System Itself
The whole system fits under your sink and connects with quick-connect fittings. Four quick-change twist cartridges handle the filtration stages, and a UV chamber sits inline between them. There’s no bulky storage tank, so water is purified on demand—ideal for busy West Little River homes.
Stage 1 traps rust, dirt, and sand—helpful with Miami-Dade’s hard water and everyday sediment.
Carbon block media that reduces chlorine, odors, color, and chemicals before the membrane—great for 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—great for Miami-Dade’s hard water.
Filtration Stages
Each stage handles what the one before it left behind. UV is step four, and it’s not filtration at all—it’s there to help handle what filters can’t catch in Miami-Dade County municipal water.
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—helping reduce issues tied to hard water scale.
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. It’s included in the price on every system we install in West Little River.

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 West Little River homes dealing with Miami-Dade’s hard municipal water. 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.
