Nazava’s main filter model is the Nazava Riam which has an upper container to collect the dirty water and a lower container with a tap for the drinking water. Both containers have a volume of 16 liters. The water purifier is designed by Delft University. The water filter system is equipped with a high-quality ceramic filter which is easy to transport and replace. It is filled with activated carbon and anti-microbial silver which removes 99.9% of all bacteria and produces water that complies with WHO standards. It has a filtration capacity of up to 7,000 liters at 2-3 liters per hour.
The filter candle lasts for two years, and then needs to be replaced. The ceramic element can be used as fertilizer, but the plastic lid should be recycled.
The retail price is US $30 and the replacement filter costs US $8. It enables households to filter tap or rain water at 1/3 of the costs of boiling water and 1/8 of the cost of buying water.

Globally, 4.4 billion people have no access to treated water in their house (Dalberg, 2017). In most countries, piped water is not safe for consumption. Households either have to buy or boil their drinking water, which costs can add up to more than US $100/year. Besides, boiling water and transporting bottled water causes CO2 emissions. Globally, women carry the burden of providing drinking water to their families.
Lack of access to safe drinking water is one of the main causes for diarrhea. In 2016, diarrhea was the eighth leading cause of mortality, responsible for more than 1.6 million deaths. More than a quarter of diarrhea deaths occurred among children younger than 5 years, and about 90% of diarrhea-related deaths occurred in South Asia and Sub-Saharan Africa. (Lancet, 2018)
Indonesia has a population of 260 million people but 72% of the population gets their water from a well. As there is no sewage system most of this water is contaminated with e-coli bacteria. For the 150 million Indonesians that earn less than $7 per day, this causes diseases, leads to high expenses to obtain safe drinking water, disproportionately affects women, and harms the environment.
The problems that Nazava Water Filters address are:
- Diseases caused by lack of access to safe drinking water and unsafe storage of boiled water;
- High costs of obtaining safe drinking water;
- Disproportionate burden for women to provide safe drinking water to their families;
- Greenhouse gas emissions caused by boiling water on wood or LPG; and
- The distribution of the technology to remote areas.
