will be the mechanism by which the smallest particles are captured at decreased air velocities. As polluted air passes through the filter media the smallest particles move erratically or an in zig-zag pattern from higher concentrated parts, this is known as Brownian Motion.
In hospitals and clinics, airborne pollutants can pose significant hazards to clients, especially All those with compromised immune devices. A similar goes for structures for example educational institutions, exactly where there may be a constant unfold of germs, and a lot of the very same objects could be touched by many different persons.
