See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand—made for Opa-locka homes dealing with Miami-Dade’s hard municipal water.
The System Itself
Designed for Opa-locka kitchens: the system fits under your sink and connects with quick-connect fittings. Four quick-change twist cartridges handle the filtration stages, with a UV chamber inline. No bulky storage tank—water is purified on demand.
First cartridge captures rust, dirt, sand, and larger particles—helpful with Miami-Dade’s hard municipal water.
Carbon block media that reduces chlorine, odors, color, and chemicals before the membrane—helpful with Miami-Dade tap 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 Opa-locka families.
Filtration Stages
Each stage handles what the one before it left behind—helpful with Miami-Dade’s hard municipal water that can leave mineral scale behind. UV is the fourth step, and it’s not filtration at all; it addresses what a filter can’t catch.

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 hard municipal water common across Miami-Dade, including Opa-locka. 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.
