See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand for your East Mims family—helpful with moderate hardness and the warm, humid conditions that can contribute to scaling and biofilm.
The System Itself
The whole system fits under your sink and connects with quick-connect fittings—perfect for East Mims kitchens. Four quick-change twist cartridges provide the four filtration stages, and a UV chamber sits inline between them. With no bulky storage tank, water is purified on demand instead of sitting and waiting—helpful in our warm, humid climate where biofilm can be a concern.
The first cartridge traps rust, dirt, sand, and larger particles common in groundwater before anything downstream sees them.
Carbon block media that reduces chlorine, odors, color and chemicals before the membrane—great for Brevard County water.
The heart of the system—rejects dissolved solids and heavy metals, sending the concentrate to the drain.
The final cartridge polishes the water and adds beneficial minerals back for a balanced pH—great for Brevard County homes.
Filtration Stages
Each stage handles what the one before it left behind. Here in East Mims, where many homes rely on groundwater, UV is the step that goes beyond filtration to help address what filters can’t catch.
Removes rust, dirt, sand and large particles often found in groundwater.
Removes chlorine, odors, colors and chemicals—ideal for East Mims groundwater.

Four filtration stages plus UV sterilization. Steps 1 to 3 and 5 are the four filtration stages; step 4 is the built-in UV lamp for disinfection—especially valuable in East Mims’ warm, humid environment. It’s included in the price on every system we install.

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 East Mims homes that often rely on groundwater. 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—especially helpful in our warm, humid Space Coast conditions that can contribute to biofilm growth—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.
