See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand—built for White City living in Miami-Dade’s tropical climate.
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 White City kitchens.
Stage 1 cartridge—catches rust, dirt, sand, and larger particles before they reach the rest of the system.
Carbon block media that reduces chlorine, odors, color, and chemicals before the membrane—great for 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 Miami-Dade homes.
Filtration Stages
Each stage handles what the one before it left behind. Here in White City, hard water can leave mineral scale behind, and UV (step four) adds protection for what filters cannot catch.
Removes rust, dirt, sand, and large particles—helpful for hard water in White City.
Removes chlorine, odors, colors and chemicals for cleaner-tasting water in White City.

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—great for year-round use in South Miami-Dade’s warm, humid climate. 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.
