Cleanroom apparel refers to specialized garments designed for individuals working in cleanroom environments—spaces where strict control of airborne particles, microbes, and other contaminants is critical. Since human presence is the leading source of contamination in these settings, such apparel plays a vital role in preventing the release of particles into the environment. To be effective, cleanroom garments must be lint-free, non-shedding, and often made from antistatic or electrostatic discharge (ESD)-safe materials. They are available in sterile or non-sterile forms and may be either disposable or reusable, depending on the application. Proper use of cleanroom apparel helps maintain product quality, prevent contamination, ensure compliance with regulatory standards (such as FDA, GMP, and ISO), and protect personnel working in controlled conditions. These garments are designed to meet varying ISO cleanroom classifications, ranging from ISO Class 1 to ISO Class 9.
