To evaluate the acceptability, performance, and health impact of household hollow fiber ultrafilters on drinking water quality and infant diarrheal illness.
Conducted a cluster-randomized evaluation across 10 intervention and 10 comparison villages in Kenya, enrolling households with infants under 12 months old.
Enrolled 92 infants in intervention households receiving hollow fiber ultrafilters and 74 infants in comparison households.
Conducted biweekly home visits for 1 year to record water treatment practices and diarrhea episodes, alongside testing stored water every 2 months for Escherichia coli.
Stored water tested positive for E. coli in 45.7% of intervention households compared to 97.3% of comparison households (OR: 0.42, 95% CI: 0.24, 0.74).
Adjusted odds of reported infant diarrhea did not differ significantly between intervention and comparison groups (OR: 1.19, 95% CI: 0.74, 1.90).

Implication

Randomized trial finds water ultrafilters reduce bacterial contamination without lowering diarrhea in infants, indicating that filtration alone is insufficient.
