Objective: We sought to examine a community engagement (CE) strategy, defined as a monetary contribution, on water filter usage Design: A natural, quasi-experimental study was conducted in Guatemala following the distribution of water filters. Households in the 2014-2015 group (free water filter) were compared with households in the 2018-2019 group (CE strategy: US$5.50 for water filter) Sample: One-year post-distribution, the comparison group (n = 56) and intervention group (n = 38) completed a survey on family health and water filter use Results: Households in the CE group had almost five times higher odds (OR = 4.7, p = .022) of having a working water filter 1 year later. Using a multivariable logistic regression model, the single best predictor to explain working water filters was the CE strategy Conclusions: CE strategies that support ownership and dignity might sustain public health initiatives, in conjunction with collaborative international partnerships. Future research could include linking villages with local and international organizations that support safe drinking water initiatives.

Despite the United Nations declaration that safe drinking water is a human right, many countries have not achieved this goal (World Health Organization [WHO], 2015). In Guatemala, lack of potable water contributes to a child mortality rate of 26/1000; one of the highest child mortality rates in Central America (United Nations Children's Fund, 2018). As the most populous country in Central America, Guatemala is challenged by high rates of poverty, violence, and ethnic inequalities. Guatemala is also the top remittance (transmittal of money) recipient in Central America, because of a large emigrant community in the United States (World Factbook, 2020).Access to safe drinking water through point-of-use water filtration systems has reduced the incidence of diarrhea in many parts of the world. Reduced incidence of diarrhea subsequently lowers infant and child mortality in developing countries (Clasen et al., 2015). In the field, recommended point-of-use water filters are designed with silverimpregnated clay pots that have been shown to eliminate 99.88% of toxins in contaminated water (van Halem et al., 2007). Even though household water filters have had a positive impact on community health, their long-term sustainability is less well known. For example, 652
