Indoor water filtration technologies have been implemented in various rural communities across Nigeria to improve water quality and public health outcomes. A cross-sectional study was conducted in four rural communities. Indoor water samples were collected at households equipped with filtration devices and compared to those from non-filtration households. Water quality parameters were measured using standard analytical methods, and data on reported health outcomes were collected through structured interviews. Significant differences (p < 0.05) in turbidity levels between filtered and unfiltered water samples were observed, with a mean difference of 28.5 NTU (±13.6). The implemented indoor water filtration technologies significantly improved water quality parameters, particularly turbidity. Further studies should focus on the long-term sustainability and efficacy of these technologies in various rural settings across Nigeria. Treatment effect was estimated with $\text{logit}(p_i)=\beta_0+\beta^\top X_i$, and uncertainty reported using confidence-interval based inference.
