See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand for your Atlantis family.
The System Itself
The whole system fits under your sink and connects with quick-connect fittings—perfect for Atlantis homes. Four quick-change twist cartridges handle the filtration stages, with a UV chamber inline. There’s no bulky storage tank, so water is purified on demand instead of sitting and waiting.
The first cartridge catches rust, dirt, sand, and larger particles before anything downstream sees them—helpful with hard municipal water in Palm Beach County.
Carbon block media that reduces chlorine, odors, colors and chemicals before the membrane—ideal for Palm Beach County water.
The heart of the system, rejecting dissolved solids and heavy metals and sending the concentrate to the drain—great for hard Palm Beach County water.
The final cartridge polishes the water and adds beneficial minerals back for a balanced pH—nice for everyday Atlantis drinking water.
Filtration Stages
Each stage handles what the one before it left behind—ideal for Palm Beach County water. 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 for Atlantis homes in Palm Beach County.
Reduces chlorine, odors, colors and chemicals in Atlantis tap water.

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 Atlantis homes in Palm Beach County. 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.
