Nazava Water Filters

Company Profile

Safe Drinking Water, for Everyone, Everywhere

Nazava Water Filters PTE LTD is a social enterprise incorporated in Singapore with operations in Kenya & Indonesia. Nazava started as an Indonesian social enterprise but decided to move to Singapore to increase impact at a global scale. Nazava is mentioned in the DBS-NUS list of 100 social enterprises to watch for in Asia.

In 2016 Nazava was semi-finalist in the DBS NUS Social Venture Challenge for Asia. In 2022 Nazava won the top prize in the Bayer Social Innovation Awards for Asia Pacific.

Our Cause

Worldwide, 4.4 billion people do not have access to safe drinking water in their home.

Every year more than half a million children pass away because of a constant exposure to bacteria in dirty drinking water. Especially women spend a lot of time on collecting and treating water. Moreover, this dirty water is more expensive than clean water. In the slums of mega cities like Jakarta you easily pay 5 to 10 times more for water than what you would pay in London. [Source: UN]

Therefore, we target the 4.4 billion people or around 1 billion low-income families that do not have access to safe drinking water in their homes.


We believe that access to clean water should not be defined by economic means. Every single person should be able to afford to protect their family from disease and to live happy, healthy lives.


Everyone everywhere should have access to safe and affordable drinking water. It is our mission to be the world’s premier water filter company of safe and affordable water filters. We focus on marketing the best available water filters for the lowest possible price, especially targeting the base of the (income) pyramid.

By providing safe drinking water, we also tackle climate change, health, poverty, gender equality, and reduce plastic waste (read more about our impact here).  As a social enterprise, we reinvest at least 75% of our profit to achieve sustainability, grow our reach and ensure the fulfillment of our mission.

How we do it

Safe Drinking Water

The filtered water is safe to drink and fulfils the WHO standards. Our filtration technology has been successfully used during the cholera outbreaks in Haiti and Zimbabwe. Test reports of more than 30 laboratories can be checked here.

Cost and Life Saving

The costs of obtaining safe drinking water are high. Boiling water in rural areas and refilling gallons in urban areas remain the most popular options to get safe drinking water.

The Nazava Water Filters are eight times cheaper than buying water and three times cheaper than boiling water.

Besides, per year 6 out of every 1000 children in Indonesia below five die of waterborne diseases such as diarrheas. Boiling water on wood causes enormous amounts of carbon emissions.

Nazava water filters help in fighting diarrheas and when used as an alternative to boiling water they are an effective tool against global warming.

As part of our carbon credit verification process, we are certified to directly impact SDGs 1, 3, 5, 6, 8, 13, & 15. Learn more here.
