See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand for your Port St. Joe home—great for tackling moderate mineral content and everyday taste.
The System Itself
The whole system fits under your sink and connects with quick-connect fittings. Four quick-change twist cartridges provide the filtration stages, with a UV chamber inline. With no bulky storage tank, you get purified water on demand—ideal for Port St. Joe’s coastal, humid climate.
The first cartridge catches rust, dirt, sand, and larger particles—helpful with coastal mineral content in Port St. Joe.
Carbon block media that reduces chlorine, odors, colors, and chemicals before the membrane—great for coastal water.
The heart of the system—rejecting dissolved solids and heavy metals, then sending the concentrate to the drain.
The final cartridge polishes the water and adds beneficial minerals back for a balanced pH—great for everyday drinking.
Filtration Stages
Each stage handles what the one before it left behind—helpful in a coastal Gulf climate like Port St. Joe, where mineral content can contribute to scale. UV is the fourth step in the sequence and the one stage that is not filtration at all—it’s 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—great for Port St. Joe homes dealing with coastal salt air and moderate mineral content. 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—plus added peace of mind when hurricane season brings outages.
