Drinking water treatment technologies designed for low- and middle-income countries (LMICs) and humanitarian contexts are critical to provide safer drinking water and reduce the burden of diarrheal disease. Among water technologies to treat water at the point of use, Household Water Treatment (HWT) filters (e.g., membrane filters and ceramic water filters) have received increasing attention because they are durable products, and they provide a physical barrier to remove microorganisms without altering water taste and odor.However, critical knowledge gaps exist for HWT filters and their use in LMICs and humanitarian contexts. Therefore, the focus of this research was to address and fill four of these evidence gaps by conducting the following work: 1) a laboratory research investigating fouling on commonly-distributed membrane filters to promote their use in LMICs and humanitarian contexts; 2) a laboratory research assessing ceramic water filters V. cholerae removal efficacy to encourage their use during cholera outbreaks; 3) a modelling study defining the role of ceramic disks in determining ceramic water filters hydraulic performance to simplify laboratory testing and inform future research on the use of ceramic water filters; and, 4) a mixed-method research assessing WASH coordination outcomes and impacts to improve coordination in humanitarian contexts and ultimately improve WASH interventions including HWT filters distribution.Results from this research fill gaps of knowledge and provide new evidence on HWT filters options in LMICs and humanitarian response, showing that: 1) there is no one-size-fits-all cleaning solution for membrane filters; 2) ceramic water filters can remove V. cholerae, if sufficient silver is present; 3) disks can be used to model full-size filters; and, 4) coordination is critical to meeting response outcomes.Additionally, this work leads to the following considerations: 1) HWT filters efficacy evaluation in laboratory setting should include context-specific components; 2) laboratory HWT filters efficacy evaluation should better consider hydraulic performance assessment; 3) humanitarian contexts evolve rapidly which may directly impact research; 4) multi-disciplinary research is valuable to answer WASH-related research questions; and, 5) both UNICEF and WHO have a role in evaluating HWT technologies.As households in LMIC and humanitarian contexts rely on HWT filters to treat their drinking water and humanitarian emergencies will continue, further research, including the development of protocol for HWT filters use in humanitarian contexts and to improve HWT filters and coordination, is needed to protect vulnerable populations.
