Pollen & Mold

During pollen and mold season, the Southwest Ohio Air Quality Agency measures the daily levels of naturally occurring airborne pollutants These counts are expressed in grains per cubic meter of air for pollen levels and spores per cubic meter of air for mold levels.

Due to the COVID-19 impact, pollen and mold counting will be limited. We will be conducting pollen and mold counts to help keep you informed of natural airborne allergens as staffing permits. Check back often or follow us on Twitter or Facebook.
