Ideal ventilation and air conditioning systems are equipped with air filters. The air filter is divided into three kinds: primary effect, medium effect and high efficiency. Available according to different requirements. Use the appropriate grade of filter. General aseptic operating room air conditioning system should be set at least primary or medium effect filter. The number of ventilation and air change in the operating room should be more. When the filter efficiency at the end of the two-stage filtration system is above, the number of air change should be once per hour. If a HEPA filter is installed, the number of air changes per hour should be one, so that the number of bacteria in the air during the operation can be kept below.
