Pollen & Mold

Pollen and mold counting has concluded for 2021. We'll resume in February 2022 as weather conditions permit.

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.
