> Water filter independently tested: Lab tests and CE-certified studies prove MAUNAWAI's effectiveness. View the scientific results overview.

*Science & Research*

## Trust is built through transparency.

That is why we have our filter system regularly tested by independent institutes – through long-term studies, physico-chemical analyses and biophysical tests. The results speak for themselves: top of the class in independent comparative tests, excellent removal of harmful substances and water quality that comes remarkably close to natural cellular water. Here you will find the evidence to back up our promises.

**Winner of the comparison test**

Altroconsumo, Italy’s largest consumer organisation, has tested 14 water filters. The Kini achieved the highest overall rating.

**CE certification**

European safety and hygiene standards in accordance with EN 17093:2018 – tested and monitored annually.

**Dark-field microscopy**

Dark-field microscopy reveals what measurements alone cannot show: the structural quality of our water.

**Kini Long-Term Study**

Three months, daily filtration, the same cartridge – what the IIREC long-term study found out about our filter system.

**Physical and chemical analysis**

Nitrates, heavy metals, pesticides, trihalomethanes – substances that our filter system has been proven to remove from your water.

**Water Resonances**

A vital frequency of 22.5 Hz and properties similar to those of intercellular fluid at 61.0 Hz – as revealed by IIREC resonance spectroscopy.
