How H14 HEPA Filters Work

H14 HEPA filters operate through a combination of interception, impaction, and diffusion mechanisms to capture airborne particles. Interception traps particles that come into close contact with the filter fibers, while impaction captures larger particles that collide directly with the fibers. Diffusion affects smaller particles, causing them to move erratically and increasing their chances of being captured. Constructed from a dense mat of glass microfiber or synthetic fibers, these filters maintain low air resistance to ensure efficient airflow. The multi-layered design enables particle retention at various depths within the filter media, ensuring highly effective filtration.
