When the biggest particles are passing via this pathway, the bundles of fibers behave like a kitchen sieve which physically blocks the particles from passing by. Having said that, when scaled-down particles pass Using the air, since the air twists and turns, the smaller particles are unable to sustain While using the movement with the air and therefore they collide While using the fibers. The smallest particles have hardly any inertia and so they often shift across the air molecules like they are bombarded by these molecules (Brownian movement).
is the most common filter mechanism and occurs if the particle is just too massive to suit involving the filter fiber Areas.
This worth is demonstrated in sections per million (ppm) and is also directly linked to the efficiency. The ‘Efficiency’ signifies The share of MPPS particles that a filter will take in or intercept.
