Clean rooms are specialized areas where the number of airborne particles, as well as environmental factors such as temperature, humidity, and pressure, are strictly controlled. They are commonly used in sensitive     manufacturing processes such as pharmaceuticals, electronics, biotechnology, and medical device production. To prevent contamination of products, clean rooms utilize ventilation systems with HEPA/ULPA filters, antistatic   materials, and special clothing. These environments ensure the safe execution of production and testing processes that require high levels of hygiene.
