See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand for your Perdido Key home.
The System—Built for Perdido Key
The whole system fits under your sink and connects with quick-connect fittings. Four quick-change twist cartridges provide the four filtration stages, and a UV chamber sits inline between them. There’s no bulky storage tank, so your Perdido Key water is purified on demand—not sitting and waiting.
The first cartridge—catching rust, dirt, sand, and large particles before anything downstream sees them.
Carbon block media that removes chlorine, odors, colors, and chemicals ahead of the membrane—great for Perdido Key tap water.
The heart of the system, rejecting dissolved solids and heavy metals and sending the concentrate to the drain—ideal for Perdido Key kitchens.
The final cartridge, polishing the water and adding beneficial minerals back for a balanced pH—great for Perdido Key drinking 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.

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 Perdido Key homes. 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.
