A cleanroom mask, also known as a cleanroom face mask, is a type of protective equipment used in cleanroom and controlled environment manufacturing and research facilities. It is designed to prevent contamination of the environment and protect the wearer from the particles and contaminants present in the controlled environment. Cleanroom masks are typically made of materials that minimize shedding and particle generation, and they may have additional features such as filtration and antistatic properties. They are an essential part of maintaining the cleanliness and safety of the controlled environment.
