See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand for your Miami Lakes family.
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, with a UV chamber inline. No bulky storage tank—so you get purified water on demand instead of water sitting in a tank in Miami Lakes heat and humidity.
The first cartridge traps rust, dirt, sand, and larger particles before anything downstream sees them.
Carbon block media reduces chlorine, odors, color, and chemicals before the membrane—ideal for Miami-Dade tap water.
The heart of the system—rejecting dissolved solids and heavy metals, then 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—especially helpful with Miami-Dade County’s typically hard municipal water. UV is the fourth step in the sequence and the one stage that is not filtration at all; it is there to deal with what a filter cannot catch.
Removes rust, dirt, sand, and large particles from Miami-Dade’s municipal water.

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 Miami Lakes homes. 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.
