See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand—ideal for Harbor Beach’s humid, coastal lifestyle.
The System Itself
The whole system fits under your sink and connects with quick-connect fittings. Four quick-change twist cartridges carry the four filtration stages, and a UV chamber sits inline between them. There is no bulky storage tank, so the water is purified on demand rather than sitting and waiting—great for humid, coastal Harbor Beach homes.
The first cartridge catches rust, dirt, and sand—helpful in Harbor Beach’s coastal conditions before anything downstream sees it.
Carbon block media that reduces chlorine, odors, colors and chemicals ahead of the membrane.
The heart of the system, rejecting dissolved solids and heavy metals and sending the concentrate to the drain.
The final cartridge, polishing the water and adding beneficial minerals back for a balanced pH.
Filtration Stages
Each stage handles what the one before it left behind. UV is step four, and it is not filtration at all - it is there to handle what a filter cannot catch.
Removes rust, dirt, sand and large particles—ideal for Harbor Beach coastal conditions.
Reduces chlorine, odors, colors and chemicals.
Removes up to 99% of dissolved solids, heavy metals and more.
Kills 99.99% of bacteria, viruses and microorganisms.
Adds beneficial minerals for a balanced, healthy pH.
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, which is not filtration but disinfection—and it’s included in the price on every system we install in Harbor Beach.

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 Harbor Beach homes in a humid subtropical, coastal environment. 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. Built for coastal Florida conditions where salt-air corrosion can be tough on outdoor plumbing and filtration components.
