See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand—built for Key West living and our coastal conditions.
The System Itself
The whole system fits under your sink and connects with quick-connect fittings. Four quick-change twist cartridges handle the filtration stages, with a UV chamber inline. No bulky storage tank—so your water is purified on demand instead of sitting, which is ideal in Key West’s warm, humid climate.
The first cartridge catches rust, dirt, sand, and larger particles—helpful in coastal conditions like the Florida Keys.
Carbon block media that reduces chlorine, odors, color and chemicals before the membrane—great for Key West tap water taste.
The heart of the system, rejecting dissolved solids and heavy metals and sending the concentrate to the drain.
The final cartridge polishes the water and adds beneficial minerals back for balanced pH—great for everyday drinking in Key West.
Filtration Stages
Each stage handles what 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’s there to deal with what a filter cannot catch.
Removes rust, dirt, sand and large particles—great for coastal Keys conditions.

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 West kitchens where space matters. 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. It’s a smart choice for Monroe County homes where salt air and coastal conditions can be tough on plumbing, and storm season can impact water quality.
Purified water makes clearer, better-tasting ice for every drink you pour—perfect for warm Key West days.
A full cartridge set is about 8,000 bottles of water—right from your Key West tap.
Ultra-pure water with UV protection, for the things you’re most careful about in Key West.
Odor-free water with balanced pH brings out more flavor in everything you brew—from morning coffee to iced tea.
The tankless build is compact, so you keep the cabinet space a storage tank would take—great for Key West kitchens.
Four twist cartridges that swap out in seconds, with no tools and no mess.
