Philly's Pollen, Ragweed, and Mold Count Source

Since 1990 The Asthma Center has been the Philly region's source for daily pollen, ragweed and mold counts. In 2020 we installed a new, revolutionary artifical intelligence powered pollen sensor - the only one of it's kind in Philadelphia, and one of the few in the Northeast US. With this new pollen technology, we can publish live pollen counts and forecasts throughout the spring and fall allergy seasons.

Our previous counts were obtained by manual analysis and interpretation of pollen samples by a technician. The analysis was done daily and resulted in reporting lags of up to 24 hours, and was not available when the office was closed (for instance on weekends). The new counts come from machine-learning equipped sensors that automatically convert air samples into pollen forecasts. We will publish the data on this page, and distribute daily snapshots through our email subscription service. This will give allergy sufferers constant access to the data they really need: pollen and mold counts that reflect what is in the air now, not yesterday. For those who want to plan outdoor activities, this is the most reliable way of using current pollen data to make informed decisions about spending outdoor time.
