See the purity, trust the technology. A tankless under-sink system delivering ultra-pure, clean, refreshing water on demand for your South Miami family.
The System Itself
Designed to fit neatly under your sink in South Miami with quick-connect fittings. Four quick-change twist cartridges handle the filtration stages, with an inline UV chamber. With no bulky storage tank, you get purified water on demand instead of water sitting and waiting.
The first cartridge traps rust, dirt, sand, and larger particles—helpful with Miami-Dade’s hard water and scale-prone plumbing.
Carbon block media that reduces chlorine, odors, colors and chemicals before the membrane—great for Miami-Dade water.
The heart of the system—rejects dissolved solids and heavy metals, sending the concentrate to the drain.
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 leaves behind—helpful with hard Miami-Dade County water where scale is a common concern. UV is step four, and it’s not filtration at all; it targets what a filter can’t catch.
Removes rust, dirt, sand and large particles—great for Miami-Dade water.
Removes chlorine, odors, colors and chemicals common in Miami-Dade tap water.
Removes up to 99% of dissolved solids, heavy metals, and more—helpful for Miami-Dade’s hard water.
Kills 99.99% of bacteria, viruses and microorganisms.
Adds beneficial minerals for a balanced, healthy pH.
Four filtration stages plus UV sterilization. Steps 1–3 and 5 are the four filtration stages; step 4 is the built-in UV lamp for disinfection (not filtration)—included in the price on every system we install in South Miami.

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 South Miami kitchens. 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, helping reduce the minerals behind Miami-Dade’s hard-water scale, 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.
