Overview

About the Thirst RO — Restore™ Alkaline System

The Thirst RO Restore adds a 5th alkaline remineralization stage to the proven RO purification platform. After removing 90%+ of dissolved solids, the Restore passes purified water through a mineral cartridge that reintroduces beneficial trace minerals and electrolytes — calcium, magnesium, and potassium — raising the pH to a healthy alkaline level. The result is drinking water that's both ultra-pure and mineral-enriched, with a smoother, more natural taste than standard RO water.

How It Works

6-stage purification with remineralization

The first five stages are identical to the Thirst RO Pure — sediment pre-filtration, carbon pre-filtration, RO membrane purification, and carbon polishing. The sixth stage adds an alkaline remineralization cartridge containing natural mineral media that dissolves trace amounts of calcium, magnesium, and potassium back into the purified water. This raises the pH from the slightly acidic range typical of RO water (6.0–6.5) to a balanced alkaline level (7.5–8.5).

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 Restore

Standard RO water is extremely pure, but some people find it tastes flat or slightly bitter due to the removal of all minerals. The Restore addresses this by reintroducing trace minerals that improve taste and mouthfeel while maintaining the purity benefits of reverse osmosis. It's also the right choice if you prefer alkaline water for health reasons — the remineralization stage raises pH naturally using mineral media, not chemical additives.

Balanced hydration for Arizona's dry climate

Arizona's arid climate means residents need to stay well-hydrated year-round. Water that tastes better gets consumed more — and the Restore's mineral-enhanced, alkaline water has a smoother, more satisfying taste than standard RO water. The remineralization stage adds back the beneficial minerals (calcium, magnesium) that Arizona tap water actually has in abundance but that are removed along with harmful contaminants during the RO process.

Ideal For

Families who prefer the taste of spring water

Anyone interested in alkaline water without chemical additives

People who find standard RO water tastes flat

Health-conscious households focused on hydration

What customers say about Thirst RO

Mike came to my home today to inspect and perform maintenance on my water softener and RO system. He was punctual, friendly, and efficient. I highly recommend calling Clear Water Solutions/Absolute Osmosis if you’re serious about having fresh, clean water without all the buildup from the hard water here in Red Rock Village. Two thumbs up! Great job Mike!

We live in Sun Lakes AZ, and after extensive research we decided to go with Clear Water Concepts, there upfront pricing on there website and a very thorough explanation of the system was exactly what we were in need of. On installation day our technician Ted was on time and very informative regarding the installation process. Ted installed a water softener and RO system in our home, the work performed was very impressive and detailed oriented. We are very pleased and would highly recommend them.

Clear Water Concepts installed both a water softener and an RO system for us and we couldn't be more pleased. Both Moses and Mike were fantastic to work with - friendly, efficient and knowledgeable. The communication from the time of quote through install was great. Our RO water tastes delicious and the soft water makes a noticeable difference in our hard water in Vail, AZ. Highly recommend this company & their products!
