Hospital clean rooms are commonly used in modular operating rooms, ICUs, isolation rooms, and other medical facilities. Medical clean rooms are a professional and important industry, especially modular operating rooms that have strict requirements for air cleanliness. The modular operating room is an important part of the hospital and consists of the main operating room and auxiliary areas. The optimal cleanliness level around the operating table is Class 100. It is usually recommended to install a HEPA filtered laminar flow ceiling of at least 3*3m above the operating table to provide coverage for the operating table and medical staff. Creating a sterile environment can reduce patient infection rates by more than 10 times, thereby reducing reliance on antibiotics and minimizing potential damage to the human immune system.
