How Do HEPA Filters Capture 0.1 Micron Particles?
HEPA filters capture 0.1 micron particles through a combination of mechanisms including interception, inertial impaction, and diffusion.
-
Interception: This process occurs when particles follow the airflow and come close to the fibers of the filter. If they encounter a fiber, they stick to it. Studies, such as those by Qian et al. (2010), show that interception effectively captures particles larger than 0.1 microns.
-
Inertial impaction: Larger particles tend to resist changes in motion due to inertia. When air carrying these particles flows through the filter, the particles collide with the fibers and are captured. Research from the American Society of Mechanical Engineers indicates that this method is highly efficient for particles between 0.1 and 1 micron in size.
-
Diffusion: Smaller particles, particularly those below 0.1 microns, move erratically due to Brownian motion. This random movement increases their chances of colliding with fibers in the filter. A study by Zhang et al. (2018) discusses how diffusion enhances the capture efficiency of HEPA filters for ultrafine particles.
HEPA filters are designed with densely packed fibrous materials that maximize these capture mechanisms. The effectiveness of HEPA filters in removing particles is often rated at 99.97% for particles as small as 0.3 microns, which effectively includes the smaller 0.1 micron particles due to the combined action of these mechanisms.
