See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand—made for Key Largo living in the Florida Keys.
The System Itself
The whole system fits under your sink and connects with quick-connect fittings. Four quick-change twist cartridges deliver the four filtration stages, with a UV chamber inline. There’s no bulky storage tank—so in hot, humid Key Largo, you get purified water on demand instead of water sitting and waiting.
The first cartridge catches rust, dirt, sand, and larger particles—helpful with Keys plumbing exposed to salt air and humidity.
Carbon block media that reduces chlorine, odors, colors, and chemicals before the membrane—ideal for Keys water systems.
The heart of the system, rejecting dissolved solids and heavy metals and sending the concentrate to the drain—helpful with hard water in Key Largo.
The final cartridge polishes the water and adds beneficial minerals back for a balanced pH—great for Key Largo drinking water.
Filtration Stages
Each stage handles what the one before it left behind. UV is the fourth step, and it’s not filtration at all—it’s added protection for what filters can’t catch, a smart upgrade for Keys water setups.

Product Assurances
Better-tasting, odor-free water for drinking, cooking, and everyday use in Key Largo.
Tankless purification as you draw—no storage tank and no waiting, even in hot, humid Key Largo.
The built-in UV lamp helps eliminate bacteria, viruses, and microorganisms a filter can’t 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—ideal for Key Largo homes where many rely on storage tanks or treatment systems due to limited freshwater supply in the Keys. 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.
Purified water makes clearer, better-tasting ice for every drink you pour—perfect for hot, humid Key Largo days.
A full cartridge set equals about 8,000 bottles of water—right from your Key Largo tap.
Ultra-pure water with UV protection, for the things you’re most careful about in your Key Largo home.
Odor-free water with balanced pH brings out more flavor in everything you brew—coffee, tea, and more.
The tankless build is compact, so you keep the cabinet space a storage tank would take—great for Key Largo kitchens.
Four twist cartridges swap out in seconds—no tools, no mess, no hassle.
