See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand for your South Miami Heights home—great for Miami-Dade’s hard water.
The System Itself
The whole system fits under your sink and connects with quick-connect fittings. Four quick-change twist cartridges carry the four filtration stages, and a UV chamber sits inline between them. There is no bulky storage tank, so the water is purified on demand rather than sitting and waiting—ideal for busy South Miami Heights homes.
Stage 1 catches rust, dirt, sand, and larger particles—helpful with Miami-Dade water that can leave gritty buildup.
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—helpful with Miami-Dade’s hard water.
The final cartridge polishes the water and adds beneficial minerals back for a balanced pH—great for everyday drinking in South Miami Heights.
Filtration Stages
Each stage handles what the one before it leaves behind. UV is the fourth step in the sequence—and it’s not filtration at all. It’s there to handle what filters 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 South Miami Heights 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.
