# Our technology

> The PI water filter by MAUNAWAI mimics natural filtration processes. PI technology transforms tap water into vibrant, mineral-rich drinking water.

*Our technology*

## In nature

As water flows through layers of rock, it is filtered, enriched with minerals and revitalised by movement. This process takes years – and transforms rainwater into living spring water. Our Pi technology replicates this exact process. No electricity, no chemicals, no pressure. Discover how we bring nature into your home.

**The five principles**

Filtration, information, optimisation, harmonisation, bioavailability – what lies behind each step.

**Inspired by nature**

How a stream flows back to its mountain source – the journey of your water through our filters

**What is Pi technology?**

From Japanese bud research to the further development of MAUNAWAI – the origins of our technology.

**What sets us apart**

No electricity, no chemicals, no salts, no ion exchangers – why MAUNAWAI isn’t your average water filter.

**MAUNAWAI vs. Osmose**

Why we preserve minerals rather than removing them – and what that means for your water.

**Made in Germany**

In-house jug production, in-house cartridge development – how we ensure quality
