HOW AIR FILTERS WORKS

How do filters remove particles from the air and reduce exposure - especially the small ones? As this Risk Bites primer shows as it dives into the science of aerosol particle capture, it may not be how you think!

Air filters are an important tool for protecting health, improving air quality, and reducing air pollution by removing potentially harmful particles from the air you breathe. But how they work isn't that intuitive -- especially at small particle sizes.

This introduction to the aerosol science of filtration is relevant to workplace safety and public health and is suitable for K-12 as well as college and professional audiences interested in how filters work.
