The Cleaner Air Spaces Act of 2025 directs the Administrator of the Environmental Protection Agency (EPA) to provide grants to air pollution control agencies. These grants are intended to fund the implementation of a cleaner air space program , with a maximum of $3,000,000 per agency and a requirement for at least one grant to a Tribal agency. The program's primary goal is to protect vulnerable populations from the health impacts of wildland fire smoke. To receive a grant, agencies must submit a proposal detailing their plan, including a required partnership with a community-based organization . The program mandates the establishment of at least one clean air center in areas at risk of wildland fire smoke, which must be accessible and staffed during smoke events. Additionally, agencies must distribute a minimum of 1,000 free eligible air filtration units and one replacement filter to covered low-income households, along with educational materials on their proper use. Covered households are defined as those in low-income communities with individuals at high risk and vulnerable to negative health effects from wildland fire smoke. Agencies are also required to collect data on distributed units and survey recipients regarding their experience and understanding of the program. The bill authorizes $30,000,000 for fiscal years 2026 through 2028 to carry out these provisions, with the EPA Administrator required to report to Congress on the program's effectiveness and potential for expansion.
