A cleanroom is a controlled space that minimizes the introduction of contaminants into the air, surfaces, and personnel. These environments are critical to processes where even minute particles can adversely impact product quality or safety. Cleanrooms employ specialized systems such as HEPA filtration, positive air pressure, and controlled access

Cleanroom classification systems are a standardized framework for defining and achieving specific levels of air cleanliness. These systems determine cleanroom environments based on the number of contaminants allowed per unit volume of air. By adhering to established classification standards, such as ISO 14644 or Federal Standard 209E, facilities ca
