What is the purpose of a HEPA filter in an operating room?

A) To provide a pleasant scent in the room.
B) To remove 99.97% of particles larger than 0.3 micrometers.
C) To increase the humidity in the room.
D) To improve lighting quality in the room.

The correct answer is: B) To remove 99.97% of particles larger than 0.3 micrometers.

In an operating room, the purpose of a HEPA filter is to remove 99.97% of particles larger than 0.3 micrometers. This is crucial in maintaining a clean and sterile environment to reduce the risk of infections during surgical procedures. HEPA filters are highly efficient in trapping small particles and airborne contaminants, ensuring the air quality in the operating room is of the highest standard to protect both patients and medical staff. The other options are incorrect because: A) HEPA filters do not provide a pleasant scent in the room. Their primary function is to purify the air by trapping particles. C) HEPA filters do not increase the humidity in the room. They focus on air filtration. D) HEPA filters do not serve to improve lighting quality in the room. Their main role is air purification.
