The System Itself

FOUR TWIST CARTRIDGES, ONE UV CHAMBER, NO TANK

The whole system fits under your sink and connects with quick-connect fittings. Four quick-change twist cartridges carry the seven 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.

PP Sediment Filter

The first cartridge, catching rust, dirt, sand and large particles before anything downstream sees them.

CTO

CTO Carbon Block Filter

Carbon block media that takes out chlorine, odors, colors and chemicals ahead of the membrane.

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, polishing the water and adding beneficial minerals back for a balanced pH.

Filtration Stages

SEVEN STAGES OF FILTRATION, PLUS UV

Each stage handles something the one before it left behind. UV is the fifth step in the sequence and the one stage that is not filtration at all - it is there to deal with what a filter cannot catch.

1

PP & Sediment Filter

Removes rust, dirt, sand and large particles.

2

Carbon Block Filter (1st)

Removes chlorine, odors, colors and chemicals.

3

Reverse Osmosis Membrane

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

4

Carbon Block Filter (2nd)

Improves taste and removes any remaining odors.

5

UV Sterilization

Kills 99.99% of bacteria, viruses and microorganisms.

6

Post Carbon Polishing Filter

Final polishing for ultra-fresh, great-tasting water.

7

Alkaline & Mineral Filter

Adds beneficial minerals for a balanced, healthy pH.

8

Final Ultra-Fine Filter

Captures any tiny particles for crystal-clear results.

Seven filtration stages plus UV sterilization. Steps 1 to 4 and 6 to 8 are the seven filtration stages; step 5 is the built-in UV lamp, which is not filtration but disinfection - it is included in the price on every system we install.

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. 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, and a second carbon block cleans up the taste. 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. Post carbon polishing, an alkaline and mineral stage and a final ultra-fine filter finish the water, putting beneficial minerals back for a balanced pH and catching any last particles. Seven filtration stages plus UV, 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.

NO MORE BOTTLED WATER

A full cartridge set is about 8,000 bottles of water, straight from the tap.

SAFE FOR BABY FORMULA

Ultra-pure water with UV protection, for the things you are most careful about.

BETTER COFFEE & TEA

Odor-free water with a balanced pH brings out more flavor in everything you brew.

SAVES UNDER-SINK SPACE

The tankless build is compact, so you keep the cabinet space a storage tank would take.

QUICK-CHANGE CARTRIDGES

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