Nazava Water filters: Bringing safe water home 

In Indonesia, the 4th most populous country in the world, more than 70% of the population relies on well water, much of which is contaminated (source). For millions of people, especially women, access to safe drinking water remains a daily struggle. The health consequences are severe: water-related diarrhea remains one of the leading causes of child mortality. 

Convinced that health begins at home, Lieselotte Heederik & Guido van Hofwegen founded Nazava in  2009 to ensure that every household can drink water safely, easily, and affordably. Nazava provides a simple, climate-smart solution that brings safe water directly to families. These innovative gravity-powered household filters, tested and certified by the World Health Organization, remove 99.9% of bacteria from almost any water source, without the need for electricity, or fuel. 

Nazava’s mission is to make safe drinking water accessible to everyone, everywhere. The filters are designed to be affordable, durable, and adapted to local realities.  550,000 people drink from a Nazava filter every day In Indonesia. 

Nazava operates through multiple sales channels that make safe water available wherever people need it most: 

• Microfinance partnerships that allow families to buy filters in affordable installments (with partners like KOMIDA,  PNM Mekaar in Indonesia) 
• E-commerce and resellers serving both rural and urban customers 
• School programs that equip classrooms with Nazava filters 

Since 2022, in partnership with Danone’s subsidiary Aqua, Nazava has installed filters in schools, benefiting over 76,000 students. A recent study found that these filters quadrupled students’ hydration levels, improving health, focus, and learning outcomes. 

Nazava is a for-profit social enterprise and a certified B Corporation, recognized for its commitment to sustainability, transparency, and measurable social impact.
