How Do HEPA Filters Work to Clean Air?

HEPA filters clean air by trapping small particles, allergens, and pollutants through a combination of mechanical filtration and impaction techniques.

HEPA, which stands for High-Efficiency Particulate Air, is a type of filter that can remove at least 99.97% of particles that are 0.3 microns in diameter. Here are the key ways HEPA filters clean the air:

• Mechanical filtration: HEPA filters capture particles using a dense mat of fibers. As air flows through the filter, larger particles get stuck to these fibers while smaller particles are trapped as well.

• Particle size trapping: HEPA filters are effective against particles of various sizes. They trap over 99.97% of particles that are 0.3 microns, which includes dust, pollen, and some bacteria. The efficiency decreases slightly for particles smaller than 0.3 microns, but they can still capture ultra-fine particles using other mechanisms.

• Impaction: HEPA filters utilize a mechanism known as impaction, where larger particles collide with fibers as air passes through. These particles lose momentum and attach themselves to the fibers.

• Diffusion: Smaller particles, especially those smaller than 0.1 microns, move erratically due to Brownian motion. This increases their chances of contact with the fibers in a HEPA filter, helping to capture them.

• Pre-filter stage: Many HEPA filter units include pre-filters that target larger particles before they reach the HEPA filter. For example, a study by the Environmental Protection Agency (EPA, 2021) states that pre-filters enhance the lifespan of HEPA filters by reducing the amount of large debris entering the HEPA stage.

• Maintaining indoor air quality: Studies indicate that HEPA filters improve indoor air quality significantly.
