See the purity, trust the technology. A tankless under-sink system that delivers ultra-clean, refreshing water on demand—great for Deering Bay families dealing with hard Miami-area municipal water.
The System Itself
Designed for Deering Bay kitchens, the whole system fits under your sink and connects with quick-connect fittings. Four quick-change twist cartridges provide the four filtration stages, with a UV chamber inline. With no bulky storage tank, you get purified water on demand—so it stays fresh in our hot, humid coastal climate.
The first cartridge catches rust, dirt, and sand—helpful with Miami-area hard water and coastal scale.
Carbon block media that reduces chlorine, odors, color, and chemicals—ideal for hard Miami-area municipal water before the membrane.
The heart of the system—rejects dissolved solids and heavy metals and sends the concentrate to the drain.
The final cartridge polishes the water and adds beneficial minerals back for a balanced pH—great for Deering Bay homes.
Filtration Stages
Each stage handles what the one before it leaves behind—ideal for Miami-Dade County’s typically hard municipal water. UV is the fourth step in the sequence, and it’s not filtration at all; it’s there to handle what a filter can’t catch.
Removes rust, dirt, sand and large particles—great for Miami-area 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 Deering Bay homes dealing with typically hard municipal water and scale buildup in our hot, humid coastal 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.
