The unit and water path: four twist cartridges provide four stages of filtration, with the UV chamber inline after the membrane.
PP

PP Sediment Filter

Stage 1 cartridge: catches rust, dirt, sand, and larger particles before they reach the rest of the system.

CTO

CTO Carbon Block Filter

Carbon block media that reduces chlorine, odors, colors, and chemicals before the membrane—great for managed on-site water.

RO

Reverse Osmosis Membrane

The heart of the system, rejecting dissolved solids and heavy metals and sending the concentrate to the drain.

ALK

ALK Mineral Alkaline Filter

The final cartridge polishes the water and adds beneficial minerals back for a balanced pH—great for island living.

Filtration Stages

FIVE STAGES OF TREATMENT, INCLUDING UV

Each stage handles what the one before it leaves behind. UV is the fourth step in the sequence—and it’s not filtration at all. It’s there to help address what filters can’t catch, which matters in a remote, on-site managed water setting like Fort Jefferson in the Dry Tortugas.

1

PP & Sediment Filter

Removes rust, dirt, sand, and large particles—helpful with on-site managed water systems.

2

CTO Carbon Block Filter

Removes chlorine, odors, colors and chemicals.

3

Reverse Osmosis Membrane

Removes up to 99% of dissolved solids, heavy metals and more.

4

UV Sterilization

Kills 99.99% of bacteria, viruses and microorganisms.

5

Alkaline & Mineral Filter

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 for disinfection. It’s included in the price on every system we install in Fort Jefferson.

BOTTLED WATER QUALITY DRINKING WATER ON TAP

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 Fort Jefferson’s remote, managed potable-water setups in Dry Tortugas National Park. 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.

CLEARER, FRESHER ICE

Purified water makes clearer, better-tasting ice for every drink you pour—perfect for hot, tropical maritime days in the Dry Tortugas.

NO MORE BOTTLED WATER

One full cartridge set replaces about 8,000 bottles of water—right from your Fort Jefferson tap.

SAFE FOR BABY FORMULA

Ultra-pure water with UV protection, for the things you’re most careful about—especially in remote Fort Jefferson.

BETTER COFFEE & TEA

Odor-free, balanced water brings out more flavor in everything you brew—great for island living in Fort Jefferson.

SAVES UNDER-SINK SPACE

The tankless build is compact, so you keep the cabinet space a storage tank would take—great for tight under-sink setups.

QUICK-CHANGE CARTRIDGES

Four twist cartridges that swap out in seconds, with no tools and no mess.
