Clean room is an environment that is commonly used in sensitive production lines such as pharmaceutical lines, sensitive electronics and microelectronics, food, hospitals, etc. In this environment, the amount of dust, aerosol germs, suspended particles and chemical vapor is kept low and controlled.
The suspended particles in clean rooms are usually displayed based on the particle size per cubic meter or cubic feet.
For example, in a clean class of 100,000, the particle size greater than 0.5 microns should be less than 100,000 per cubic foot, and the same in class 100 is less than 100 particles per cubic foot.
It should be noted that human hair has a diameter of 100 - 75 microns, which is 200 times more than a 0.5 micron particle.
