Creates a Cleaner Air Space Program at the Environmental Protection Agency to fund grants to air pollution control agencies so low‑income households and communities can protect themselves from wildland fire smoke. The program defines eligible households and filtration units, requires grant applications and program plans, funds distribution of filtration units and establishment of clean air centers, includes a tribal set‑aside, and requires a report to Congress. It authorizes $30,000,000 for fiscal years 2026–2028 and allows up to 10% of authorized funds to be used for administration.
