See the purity, trust the technology. A tankless under-sink system delivering ultra-pure, clean, refreshing water on demand—made for busy Aventura households.
The System Itself
This compact system fits under your sink and connects with quick-connect fittings—ideal for Aventura condos and homes. Four quick-change twist cartridges handle the filtration stages, with a UV chamber inline. With no bulky storage tank, water is purified on demand instead of sitting and waiting.
The first cartridge captures rust, dirt, and sand—helpful with Miami-Dade’s limestone-based hard water before it reaches later stages.
Carbon block media that reduces chlorine, odors, colors, 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’s hard water.
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—great for Miami-Dade’s hard water.
Reduces chlorine, odors, colors, and chemicals in Aventura tap water.
Removes up to 99% of dissolved solids, heavy metals, and more—helping fight scale tied to 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. It’s included in the price on every system we install in Aventura.

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 Aventura homes dealing with Miami-Dade’s typically hard, limestone-based water. 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.
