See the purity, trust the technology. A tankless under-sink system delivering ultra-clean, refreshing water on demand for Homestead Base families.
The System Itself
The whole system fits under your sink and connects with quick-connect fittings. Four quick-change twist cartridges deliver the four filtration stages, with a UV chamber inline. No bulky storage tank—so you get purified water on demand, ideal for busy Homestead Base kitchens.
First cartridge catches rust, dirt, sand, and larger particles—helpful with Miami-Dade’s hard water before it reaches your system.
Carbon block media that reduces chlorine, odors, and chemicals before the membrane—great for Miami-Dade’s municipal water.
The heart of the system—rejecting dissolved solids and heavy metals and sending the concentrate to the drain.
Final polishing cartridge that adds minerals back for balanced pH—nice for Miami-Dade’s typically hard water.
Filtration Stages
Each stage handles something the one before it left behind. UV is step four, and it is not filtration at all - it is added protection for what filters cannot catch in Miami-Dade County water.
Removes rust, dirt, sand, and large particles common in municipal lines.
Reduces chlorine, odors, colors, and chemicals from 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 back for a balanced, healthy pH.
Four filtration stages plus UV sterilization. Steps 1 to 3 and 5 are filtration; step 4 is the built-in UV lamp for disinfection—included in the price on every system we install in Homestead Base.

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 Homestead Base and the Miami-Dade municipal supply that often starts at the Biscayne Aquifer and runs hard. 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.
