Are there different types of air filtration equipment?
Most air-cleaning equipment, using gravitational and inertial methods such as filtration, washing, and electrostatic precipitation, will remove a good portion of the particulate matter in a given volume of air, yet it will not remove all of it. The deficiency is vitally important, because in a clean room, an above-average amount of cleanliness must be achieved and maintained. Air filters must be used.
