How Do HEPA Filters Work to Capture Airborne Particles?

HEPA filters capture airborne particles by using a dense mesh of fibers that trap contaminants through several mechanisms, including interception, impaction, and diffusion.

• Interception: Particles that are larger than the fiber diameter follow the airflow and tend to stick to the fibers. Studies, such as those by Al-Quait et al. (2020), show that larger particles, around 0.3 micrometers, are trapped effectively this way.

• Impaction: Larger particles do not easily change direction and collide with the fibers as the air flows through the filter. This collision causes particles to stick to the fibers. Research indicates that HEPA filters can remove 99.97% of airborne particles as small as 0.3 micrometers (US EPA, 2021).

• Diffusion: Very small particles (less than 0.1 micrometers) move erratically due to collisions with air molecules, a process called Brownian motion. This random movement increases the likelihood of these particles coming into contact with fibers, effectively capturing them.

HEPA filters are tested under standardized conditions to ensure they meet the required efficiency. The performance is validated by criteria set by organizations like the Institute of Environmental Sciences and Technology (IEST) for filters to be classified as HEPA. This ensures that they can trap 99.97% of particles at their most penetrating size of 0.3 micrometers, providing highly effective air purification.

The effectiveness of HEPA filters makes them popular in various applications, from air purifiers in homes to hospital operating rooms, to enhance air quality and reduce airborne contaminants and allergens.
