How Do HEPA Filters Function in Air Purifiers?

HEPA filters function in air purifiers by trapping small particles and contaminants, thus improving indoor air quality. This process relies on three main mechanisms: interception, impaction, and diffusion.

• Interception: As air flows through the filter, larger particles become caught in the fibers. For example, when a dust particle collides with a filter fiber, it sticks to it. Studies show that HEPA filters can capture particles as small as 0.3 microns with an efficiency of 99.97% (U.S. Department of Energy, 1993).

• Impaction: Larger particles follow a straighter path and collide with filter fibers, becoming trapped. This is effective for particles like pollen and pet dander. The larger the particle, the easier it is to trap through impaction.

• Diffusion: Very small particles, such as some viruses, move erratically due to Brownian motion. This behavior increases the likelihood of them colliding with filter fibers and being trapped. Research indicates that HEPA filters excel at capturing particles in the 0.1 to 0.3 micron range due specifically to this mechanism (Hinds, 1999).

Overall, HEPA filters require regular maintenance, including periodic replacement, to ensure they function optimally. Operating air purifiers with HEPA filters can result in a significant reduction of airborne allergens and pollutants, contributing to better respiratory health and comfort in indoor environments.
