The global need for safe and healthy drinking water is growing every year.
Clean, safe and healthy drinking water that tastes well: our lives depend on it.
The United Nations has suggested that we need 20-50 liters of safe and clean water every day for drinking, cooking and cleaning.
Yet more than one in six people worldwide – 894 million – don’t have access to this basic need.

Dutch r&d company SterWater International has developed OeauO – Pure Drinking Water, a patented counter-top appliance for domestic use that purifies tap water to the highest international standards.
The OeauO – Pure Drinking Water appliance features the unique Opresso Drinking Water Technology, harboring the Safe Water Capsule, that clears tap water from chlorine, bacteria, micro-organisms and micro-plastics.

OeauO is a sustainable brand of premium quality filtered drinking water.
Wherever you live, in India or in Spain, filling your glass with pure, crystal clear water will become as easy and affordable as brewing a cup of fine coffee.

Facts and figures
According to the World Health Organization, in 2015 only 71% of the global population (5.2 billion people) used a safely managed drinking water service, free from contamination.
Meanwhile, the consumption of bottled water has exploded, with people in the UK alone consuming 2.6 billion litres in 2014.

Most plastic bottles end up as waste in our environment, contributing to the ocean’s 269.000 tonnes of plastic soup, endangering nature, wildlife and human health.
In 2017, scientists found that 83% of the tap water worldwide is polluted by microplastics.

With OeauO, SterWater International answers the urgent demand for safe and healthy drinking water and the reduction of plastic waste. Our sustainable solution to purify tap water offers our customers easy access to safe and healthy drinking water, right in the comfort of home.

Our story
SterWater International was founded in 2016 in Breda by Maurice Visser, industrial engineer in biochemistry. Maurice Visser comes from a family of seasoned entrepreneurs, starting in 1892 with his great-grandfather, who created the family business in Oud-Beijerland. The company produced canned and frozen foods in family-owned factories, trading all over Europe through their own distribution network.

In the sixties, the company created the iconic Suzi Wan product line, focused on Asian food. In 1980, after enjoying spectacular international growth, the Suzi Wan company was sold to Mars Inc..
In the last decades, the company has focused on developing sustainable concepts for filtering waste water stream and recycling chemicals used in the photographic industry.
Today, backed by a solid track record creating innovative water filtration technology, SterWater International develops water filtration products for the consumer market. The company consists of a lean team of specialists complemented by dedicated professionals, led by CEO Maurice Visser.

Pure Dutch Design
The patented OeauO – Pure Drinking Water appliance is powered by electricity, and is not connected directly to the main water supply system. Form follows function beautifully in a clean and pure Dutch design, that fits comfortably on the counter-top.

Innovation meets comfort: the Safe Water Capsule
In the heart of the appliance rests our innovative Safe Water Capsule, crowned by our medical grade Safe Water Filter, that purifies tap water to the highest standards. Every Safe Water Capsule creates 15-20 litres of safe and healthy water.

Our patented Opresso technique filters tap water in 5 stages:

  • tap water is guided through a sediment filter that captures suspended particles like rust, sand and chalk.
  • an activated carbon block filter absorbs smaller particles (like micro-plastics), creating clear drinking water without chlorine, with a superb taste and smell.
  • the water enters the Safe Water Capsule under pressure.
  • added activated carbon particles provide superb water clarity.
  • our Safe Water Filter filters out micro-organisms and bacteria (like E. Coli, salmonella and legionella) and converts tap water into safe drinking water, while preserving healthy minerals.

A sensor indicates when the Safe Water Capsule has reached its maximum filtration capacity (max. 20 L.). Simply place a new capsule in the appliance and enjoy OeauO – Pure Drinking Water whenever you like.

Extra options to benefit health and wellbeing
The patented Safe Water Capsule offers multiple options to enrich OeauO – Pure Drinking Water,
to further benefit wellbeing and a healthy lifestyle.
Additions may include:

  • vitamins
  • minerals (like magnesium and calcium)
  • flavorings
