Overview
About the Thirst RO — Pure™ Drinking System
The Thirst RO Pure is a 5-stage under-sink reverse osmosis system that removes 90%+ of total dissolved solids from your drinking water. It delivers water that's purer than bottled — directly from a dedicated faucet at your kitchen sink. The system includes a 3.2-gallon pressurized storage tank, a designer faucet, and all components needed for professional installation. No more plastic bottles, no more water delivery — just clean, pure water on demand.
How It Works
5-stage reverse osmosis purification
The Thirst RO Pure passes water through five progressive filtration stages, each targeting different categories of contaminants. The process begins with sediment and carbon pre-filtration to protect the RO membrane, then forces water through a thin-film composite membrane with pores small enough to reject dissolved solids at the molecular level. A final carbon polishing stage ensures the water tastes clean and fresh.
1
Sediment pre-filter
Captures sand, silt, and particles down to 5 microns, protecting downstream filters and the RO membrane from premature clogging.
2
Carbon pre-filter
Removes chlorine and organic chemicals that would damage the RO membrane, extending membrane life and maintaining purification performance.
3
RO membrane
The heart of the system — a thin-film composite membrane rejects 99%+ of dissolved solids, including lead, arsenic, fluoride, nitrates, and pharmaceuticals.
4
Post-carbon polishing
A final activated carbon filter removes any residual taste or odor, ensuring every glass of water tastes clean and fresh.

We take water leak prevention seriously.
Included on all RO installs, the FLOWLOK Leak Detector is an innovative device that installs right below your RO water filtration system. Once the safety disc has detected water it expands and trips the FLOWLOK safety lever to shut off the water entering the water filtration device. Safety discs are replaceable and are economical.
Why choose the Thirst RO Pure
The Pure is for families who want exceptional drinking water quality without added features like remineralization or alkaline enhancement. It does one thing — purification — and does it at a level that exceeds what most bottled water companies deliver. At $795 with professional installation included, it's the most affordable path to lab-quality drinking water in your home. Annual filter changes are straightforward and inexpensive.
Purifying Arizona's challenging tap water
Phoenix tap water regularly tests at 400–600 ppm total dissolved solids — well above the EPA secondary standard of 500 ppm. These dissolved solids include minerals, salts, and trace contaminants that affect taste and may raise health concerns over long-term consumption. The Thirst RO Pure reduces TDS to 10–30 ppm, producing water that's dramatically cleaner than what comes from your tap. It also removes contaminants of particular concern in Arizona groundwater, including arsenic, chromium-6, and nitrates from agricultural runoff.
