The aim of the Navajo Healthy Hooghan Project is to address the issue of household air pollution and its impact on asthma symptoms in children residing in the Navajo Nation. In this project, a box fan filter (BFF) system has been designed and modeled to mitigate indoor air pollution. The study focuses on evaluating the effectiveness of the BFF in reducing particulate matter (PM) concentrations and improving respiratory health outcomes for Navajo children with asthma. The BFF system is intended to be an affordable and practical solution for households using coal/wood stove heating, which has been associated with respiratory illnesses. The project involves collaboration between Navajo Technical University (NTU), University of Arizona, University of Colorado, and University of California-Berkeley. The BFF units are manufactured at NTU, and field testing is conducted to gather preliminary data for a future clinical trial. By implementing the BFF system, the project aims to reduce indoor PM concentrations, minimize respiratory health risks, and improve the overall well-being of Navajo children. The results obtained from this study will contribute to the development of effective interventions to combat household air pollution and improve respiratory outcomes in the Navajo Nation.
