Filtration

Filtration process involves three different aspects, consisting of direct interception, inertial impaction, and diffusion. Direct Interception occurs when a particle collides with a fiber of the filter material without deviating out of the streamline flow. This mechanism tends to take place on the surface of the filter material, affecting mainly the larger particles above 1 micron in size. Inertial Impaction occurs when a particle is unable to follow the torturous path around the filter fibers and eventually collides with and adheres to one of the fibers, typically affecting particles in the 0.3 to 1 micron size range. Diffusion of Brownian Movement, as it is sometimes called, occurs with extremely small particles that tend to wander within the air stream, increasing their chances of colliding with and adhering to a fiber. This usually affects particles below 0.3 micron in size.
