High-Efficiency Particulate Air (HEPA) Filter

Purpose and mechanism of HEPA filters

HEPA filters are designed to remove extremely small particles from the air, including dust, pollen, mold spores, and even bacteria. These filters are made up of multiple layers of fine fibers that capture particles as air passes through them. The mechanism behind HEPA filters involves three main processes: interception, impaction, and diffusion. In interception, larger particles collide with the filter fibers and become trapped. In impaction, smaller particles follow the air stream and collide with the fibers, also becoming trapped. Lastly, in diffusion, the smallest particles are slowed down by the airflow, causing them to collide with the filter fibers and be captured. This combination of processes makes HEPA filters highly effective in removing airborne particles.

Importance in the aviation sector for volcanic ash

During volcanic eruptions, the ash particles released into the atmosphere can pose a serious threat to aviation safety. These tiny particles can damage aircraft engines, clog fuel systems, and impair visibility. HEPA filters play a crucial role in the aviation sector by effectively filtering out volcanic ash particles, preventing them from entering the aircraft cabin or engine. By incorporating HEPA filters into the aircraft’s ventilation system, airlines can ensure that the air breathed by passengers and crew is free from harmful volcanic ash particles. This not only maintains a comfortable cabin environment but also protects the aircraft’s vital systems from ash-related damage.
