CAMBODIA CLEAN WATER’s water filters are manufactured locally in Cambodia. We are the first project to distribute these filters in and around the Siem Reap area. These filters are ceramic with silver nitrate integrated into the ceramic material and inset in a food-water grade plastic container. These filters have been proven to function perfectly over a two-year period. For a forty dollar ($ 40 USD) donation water filter per set , we will deliver a filter to a family in need and we will send you a picture of the family you helped after delivery of the filter to their village. To emphasize, CAMBODIA CLEAN WATER is a public benefit corporation and is not organized for the private gain of any person. It is organized under the Nonprofit Public Benefit Program for charitable purposes. Its specific purposes are to provide water wells, sanitary waste disposal and aid to schools as well as other public infrastructure projects for the inhabitants of Siem Reap province.
