Nazava Water Filters provides the safest and best affordable household water treatment for those 150 million Indonesians that cannot afford to buy bottled water.
Nazava’s main filter model is a table top which has an upper container to collect the dirty water and a lower container with a tap for the drinking water. The containers are made of food-grade polypropylene (PP5). The containers are equipped with a high quality ceramic filter candle, which is 10 cm in height and 5.5 cm in width, which makes it easy to transport and replace.
The filter candle is made of ceramic, activated carbon and anti-microbial silver which removes 99.99% of all bacteria and produces water that complies with national standards. It filters up to 7000 liters and about 2-3 liters per hour.
The retail price is lower than 24 USD (the replacement filter costs 9.80USD) and
enables households to filter, tap or rain water at 1/3 the costs of boiling water and 1/9 the costs of buying water
Nazava focuses on the marketing and distribution of Indonesia’s safest and most affordable household water filters. Through a widespread sales network of micro entrepreneurs we ensure the poor rural and urban households of Indonesia have access to safe drinking water. The 330 local resellers guarantee a constant supply of the replacement filters and increase their own income as well.
With a population of 240 million people, Indonesia is the fourth biggest country in the world, but only few people in Indonesia have a continuous flow of safe and affordable drinking water in their houses. 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: 1) diseases caused by lack of access to safe drinking water and unsafe storage of boiled water; 2) high costs of obtaining safe drinking water; 3) disproportionate burden for women to provide safe drinking water to their families; 4) Greenhouse gas emissions caused by boiling water on wood or LPG 5) the distribution of the technology to remote areas
To date, we have reached over 100,000 people with access to safe drinking water.
Nazava's standard product costs 25 USD, which is cheaper than a mobile phone. The filter candle lasts for 2 years and then needs to be replaced.
The filter can only be used with fresh water. As a rule of thumb we recommend using the filter as a replacement for boiling water. Water that is chemically contaminated, brackish or containing arsenic cannot be filtered.
Support programs for customers and resellers are being developed.
