Cleanroom suits are the primary apparel worn in a cleanroom to protect against contamination. The suits are typically made of non-shedding, electrostatic dissipative (ESD) materials that are antimicrobial and resistant to tears and punctures. They cover the entire body, including the head, hands, and feet, and have hoods, boots, and gloves attached to them.

Cleanroom suits come in different classes and grades depending on the level of protection required. The class determines the number of particles allowed per cubic meter of air, while the grade refers to the level of cleanliness required. For instance, a class 100 cleanroom suit limits the number of particles up to 100 per cubic meter of air, while a class 10 cleanroom suit allows only 10 particles.

Cleanroom gloves are designed to prevent contamination from human skin or other sources. They are made of various materials such as latex, nitrile, vinyl, or neoprene, depending on the application and the level of protection required. The gloves are often sterilized and powder-free to prevent any contamination caused by the gloves themselves.

Cleanroom masks are worn to prevent the release of particles or bacteria from the user's mouth and nose. They are usually made of non-shedding materials such as polypropylene, polyester, or polycarbonate, and come in different sizes and styles. Cleanroom masks need to fit snugly on the face to provide effective protection, and they should not obstruct breathing or vision.

Cleanroom footwear is designed to prevent contamination from the soles of the shoes. They are typically made of non-shedding, anti-static, and autoclavable materials that resist puncture and abrasion. Cleanroom footwear can be either shoes or boots and must be worn over shoecovers to provide effective protection.
