Standards for Clean Room Fan Filter Units (FFU)
Latest company news about Standards for Clean Room Fan Filter Units (FFU)

The performance standards for clean room fan filter units are established by the International Organization for Standardization (ISO). ISO standards define different classifications of cleanliness and specify the maximum number of airborne particles allowed per cubic meter of air in the cleanroom environment.


The most commonly used standard for cleanroom classification is the ISO 14644 standard. This standard classifies cleanroom environments according to the maximum airborne particle size and quantity allowed in a defined volume of air.

Cleanroom fan filter units must meet and maintain the cleanliness standards established by the ISO to maintain optimal operation and prevent contamination.


Selecting the right FFU for your clean room environment is critical in ensuring effective contamination control. Several factors must be considered when selecting an FFU, including the size of the cleanroom, the airflow rate required, and the type of filter.

HEPA filters are the most commonly used filters for cleanroom Fan Filter Units due to their efficiency in removing airborne particles. When selecting an FFU, it is essential to consider the type and size of the HEPA filter to ensure that it meets the ISO standards for cleanroom classification
