The Cleaner Air Spaces Act of 2025 authorizes the EPA to provide grants, up to $3,000,000 each, to air pollution control agencies for establishing cleaner air space programs in wildfire smoke-prone areas. These programs must partner with community organizations to establish clean air centers, distribute air filtration units to low-income households, and provide educational resources. The EPA will report to Congress on program implementation and effectiveness and authorizes $30,000,000 to be appropriated to carry out this section for fiscal years 2026 through 2028.
