How Do HEPA Filters Effectively Capture Fine Dust Particles?
HEPA filters effectively capture fine dust particles by utilizing a dense mesh of fibers to trap a wide range of airborne contaminants, including those as small as 0.3 microns. This mechanism relies on three primary methods of filtration: interception, inertial impaction, and diffusion.
-
Interception: As air passes through the filter, fine dust particles follow the air stream. When these particles get close to the fibers, they can stick to them. Studies show that this method is effective for particles that are not too small or too large, enhancing the filter’s overall efficiency (Lee et al., 2018).
-
Inertial impaction: This occurs when larger particles, due to their mass, cannot easily follow the air stream around obstacles. As a result, they collide with the filter fibers and are captured. Research indicates that this method is particularly effective for capturing larger dust particles, significantly reducing the air particle concentration (Zhang et al., 2019).
-
Diffusion: This process is effective for ultra-fine particles, which tend to move erratically due to collisions with air molecules.
