Competing Interests
This study was supported in part by a grant to the London School of Hygiene & Tropical Medicine by Unilever, Ltd., which produces and sells point-of-use water treatment products including the Pureit® water filter. Unilever had no role in the design of the study, analysis of the data, or preparation and submission of the manuscript for publication. As an employee of LSHTM and otherwise, TC and JB provide research and consulting services to UN organizations, government agencies, NGOs and private companies that promote water, sanitation and hygiene interventions including point-of-use water treatment products. These include, without limitation, the World Health Organization, UNICEF, the United States Agency for International Development, the Department for International Development, Medentech, Unilever and Vestergaard-Frandsen. This does not alter the authors' adherence to all the PLoS ONE policies on sharing data and materials.
