Holder, A. Cleaner Indoor Air During Wildfires Challenge: Phase 2 Report to Solvers. U.S. Environmental Protection Agency, Washington, DC, 2024.
Impact/Purpose:
This summary provides an overview of the Cleaner Indoor Air During Wildfires Challenge: Phase 2 results. Solvers recognized in phase 1 of the challenge were invited to submit prototypes for evaluation in Phase 2. Prototypes were evaluated for their ability to safely and inexpensively reduce the concentration of smoke indoors. This report provides an overview of the evaluation results for each prototype and feedback from the judges panel. The results for each prototype are presented as individual summaries that will be provided to the solver.
Description:
This summary provides an overview of the Cleaner Indoor Air During Wildfires Challenge: Phase 2 results. This challenge was initiated through a collaborative interagency effort to bring affordable clean air to communities impacted by wildfire smoke. In Phase 1 of the challenge, solvers submitted written designs for methods to reduce wildfire smoke concentration indoors. The solvers supplying the two winning designs and six honorable mention designs were invited to submit prototypes to EPA for inclusion in Phase 2, in which prototypes were evaluated on their ability to reduce wildfire smoke concentrations in the indoor environment. Each prototype was evaluated for the following must have criteria: safe operation, no ozone generation, and demonstrated ability to reduce smoke concentrations in a controlled environment. Additionally, prototypes were evaluated on their ease of use, low initial and operating costs, and ability to cool as well as clean. The results for each prototype are presented as individual summaries that will be provided to the solver.
