The "Cleaner Air Spaces Act of 2025" authorizes the EPA Administrator to provide grants to air pollution control agencies, including Tribal agencies, for establishing cleaner air space programs. These programs will establish clean air centers, distribute air filtration units and replacement filters to covered households in areas at risk of wildfire smoke, and provide educational materials. Grant applicants must partner with community-based organizations and meet specific requirements for program implementation, data collection, and reporting. The act allocates $30,000,000 for the program from fiscal years 2026 through 2028.
