  • ‐ The air supplied to the cleanroom is of a quality that will not add significantly to the contamination within the room.
  • ‐ The air within the cleanroom suite moves from clean to less‐clean areas to minimize the undesirable movement of con taminated air. Air should move in the correct direction through doorways and the construction fabrics of the room.
  • ‐ The air movement within the cleanroom should ensure that there are no areas within the room with high concentrations of contamination.
