The chulli water purifier: acceptability and effectiveness of an innovative strategy for household water treatment in Bangladesh.
The chulli water purifier is a new household water treatment strategy in Bangladesh that relies on passing water through a stove. From households using it regularly, untreated water, sand-filtered water without heat pasteurisation, sand-filtered and heat pasteurised water, and household stored, treated water was tested. Three (19%) of 16 heat-treated samples were positive for Escherichia coli. The median log reduction from source water was > 5. Nine (56%) stored water samples were positive for E. coli, indicating recontamination. Reasons for discontinuing use among 80 of 101 persons included mechanical problems (49%), inconvenience (35%), and high cost (10%). Am J Trop Med Hyg. 2008;78(6):979-84.
