Cleanrooms are controlled environments where contaminants like dust, microbes, and other particles are filtered out in order to provide the cleanest area possible.

Most cleanrooms are used for manufacturing products such as electronics, pharmaceutical products, and medical equipment.

Cleanrooms are classified into different types depending on the sterilization level of the environment. The cleanrooms are divided into 9 classes based on the number of particles per m3 that can be measured inside. They range from ISO 1, the most sterile room, to ISO 9, considered a standard cleanroom.

ISO 8 cleanrooms are used for pharmaceutical products, manufacturing medical devices, biotech and life-science processes, that’s why they need these requirements to provide the highest quality.

  • 20 air changes per hour of HEPa filter air.
  • Less than 29300 particles/m3.
  • >0.5 microns and >1-micron size particles.
