* Particle concentration limits in particles per cubic meter (p/m³). Empty cells indicate data not specified in source.
Supply air must pass through at least three stages of filtration (primary, medium, HEPA), with HEPA filters located at the system's terminal end.
The cleanroom must have sufficient purification and air conditioning supply air volume to maintain required cleanliness levels.
Maintain necessary pressure differentials (positive or negative pressure cascades) to prevent contamination migration.
The cleanroom must have properly designed airflow patterns to ensure effective particle removal and avoid stagnant zones.
