Optional Alkaline Stage for Mineral-Rich Hydration

Looking to enhance your water even further? The hydRO offers the flexibility of adding an external alkaline filter to boost pH and reintroduce essential minerals for a healthier, more invigorating taste. The alkaline filter installation is effortless, with all necessary fittings and parts included, allowing you to customise your water for your preferences.

The Benefits of Alkaline Reverse Osmosis Water

Maintaining a balanced internal pH is often considered an important aspect of overall wellness. While the body naturally regulates blood pH within a tight range, many experts suggest that incorporating more alkaline-forming foods and water can support this balance. Excess acidity in the diet may place strain on the body’s natural buffering systems, gradually depleting alkaline mineral reserves. When this happens, the body may become more vulnerable to fatigue, inflammation, and other health concerns. Choosing mineral-rich, slightly alkaline water—such as that produced by an RO system with an alkaline filter—can be a simple, proactive step toward better hydration and long-term health.

Alkaline water can help stabilise the body’s internal pH by reducing fluctuations caused by diet and stress. The Hommix alkaline filter enriches your water with naturally sourced calcium, magnesium, potassium, and sodium ions—all 100% organic and easily absorbed by the body. While water contributes only a small portion of your daily mineral intake, the smaller molecular structure of ionised minerals makes them highly bioavailable. This not only supports gentle pH balance but also enhances hydration, helping the body absorb fluids more efficiently and recover from dehydration more effectively.
