    The Science Behind the Smog-reducing Granule

    • Smog-reducing roof house

      Improving Our Climate

      Shingles with 3M smog-reducing granules can help reduce NOx smog pollutants in the local environment.

      • 3M Smog-reducing Granules are integrated into the asphalt shingle surface at a set percentage. The granules blend together with standard color granules as part of the shingle color design pattern.  
      • These patented granules contain a photocatalytic coating layer that releases radicals when activated by the sun.
      • The radicals transform smog pollutants into water-soluble nitrate (NO3) ions that simply wash away with rainwater over time.
