See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand—ideal for Miami-Dade’s hot, humid days.
The System Itself
The whole system fits under your sink and connects with quick-connect fittings. Four quick-change twist cartridges handle the four filtration stages, and a UV chamber sits inline between them. With no bulky storage tank, you get purified water on demand—perfect for busy Miami-Dade kitchens.
The first cartridge traps rust, dirt, sand, and larger particles before anything downstream—great for Miami-Dade’s hard water.
Carbon block media that removes chlorine, odors, colors and chemicals before the membrane—ideal 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 something the one before it left behind. 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—helpful with Miami-Dade’s hard water.

The built-in UV lamp helps eliminate bacteria, viruses, and microorganisms 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—perfect for Miami-Dade homes dealing with hard municipal water and limescale. 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.
