How True HEPA Filters Work
True HEPA filters are an essential component in the realm of air purification, designed to trap and eliminate a wide range of airborne pollutants. HEPA stands for High-Efficiency Particulate Air, and to meet the criteria of “true” HEPA, filters must capture at least 99.97% of particles that are 0.3 microns in size. This includes dust, pollen, smoke, pet dander, and even some bacteria and viruses. The efficiency of HEPA filters comes from their unique structure, which consists of a dense web of fibers that creates a maze for particles to navigate, effectively preventing them from recirculating back into the air.
The operation of a true HEPA filter can be understood in terms of three key mechanisms: interception, inertial impaction, and diffusion. Interception occurs when particles follow the airflow and get caught by the fibers of the filter. Inertial impaction happens when larger particles can’t easily change direction and collide with the filter fibers. Lastly, diffusion is related to smaller particles, which move erratically due to Brownian motion, increasing their chances of encountering and adhering to the filter’s surface.
Thanks to these mechanisms, true HEPA filters can effectively reduce indoor air pollution, making them a staple in homes and offices, especially for individuals with allergies or respiratory conditions.
