Hair covers (bouffant caps) must be worn in cleanrooms to prevent contamination from hair and skin flakes. They are required to completely cover both the hair and ears, and must be properly disposed of upon exiting the cleanroom.
Cleanrooms are classified by the number and size of airborne particles allowed per cubic meter of air. The ISO 14644 standards, derived from the former US Federal Standard 209E, define these classifications. Specifically, ISO 14644-1 defines the maximum allowable concentration of particles ≥0.1 µm using a decimal logarithmic scale.

Face masks are essential PPE in cleanrooms, protecting both the wearer from inhaling hazardous particles and the environment from contaminants like breath or skin flakes. Masks should fit snugly with no gaps and provide appropriate filtration based on cleanroom requirements.
Coveralls are vital cleanroom PPE, serving as a barrier against contaminants that could compromise air quality. Cleanrooms are maintained to strict particle count standards, and wearing coveralls helps minimize contamination. Typically, disposable and available in various sizes, some coveralls feature cuffed ankles and built-in filtration systems to allow safe breathing without releasing particles into the environment.
Shoe covers prevent contaminants from being tracked into the cleanroom on footwear. Typically, shoe covers are the first piece of PPE worn when entering a cleanroom, as they create a secure barrier around the shoes and are designed to fit snugly at the ankles. Shoe covers are disposable and should be discarded upon exiting the cleanroom.
Gloves are essential cleanroom PPE, protecting both the user from harmful substances and the environment from contaminants like hair, skin, or nail particles. The type of gloves required depends on the cleanroom classification, and it's important to choose the appropriate material and specifications for each setting.
