A cleanroom is a contained space where provisions are made to reduce particulate contamination and control other environmental parameters such as temperature, humidity and pressure.
Air delivered to a cleanroom typically passes through High Efficiency Particulate Air (HEPA) filters. HEPA filters trap particles that are >0.3 micron in size. Cleanrooms maintain particulate-free air using HEPA filters, employing laminar or turbulent air flow principles.
Cleanrooms are classified according to the number and size of particles permitted per volume of air. BS EN ISO 14644 is used to classify cleanrooms in terms of the number of particles, expressed as a concentration in air volume.
The employer selects the classification to which the cleanroom is constructed. Compliance with the air cleanliness requirements specified by the employer is verified by performing specified testing procedures and by providing documentation of the results.
