Molekule has introduced an air quality score o help users quickly understand and interpret their environment. The Air Score for Air Pro is an aggregate of the 3 particulate matter levels and chemical levels. The score ranks your indoor air quality on a scale from 0-500, with 0 being the best, and 500 the worst.

The Air Quality Index is the scale the Environmental Protection Agency uses to measure and rank air pollution levels. The AQI measures ozone (O3), carbon monoxide (CO), fine particulate matter (PM 2.5,) Sulfur Dioxide (SO2) and Nitrogen Dioxide (NO2), and ranks the concentrations on a scale of 0-500, with 0 being the best and 500 being the worst. The AQI is associated with a color-coded number that indicates the warning level and advises the public on what kind of precautions to take.
