Question

What type of filters is used in the OR to reduce the microbial count?

a) HEPA filters.
b) Carbon filters.
c) Fiber filters.
d) Metal filters.

Answer 1

HEPA filters are used in operating rooms, hospital ventilation systems, and biological safety cabinets to reduce the microbial count by capturing bacteria, endospores, and viruses from the air.

Step-by-step explanation:

HEPA filters, which stands for high-efficiency particulate air filters, are used in operating rooms, hospital ventilation systems, and biological safety cabinets in laboratories to reduce the microbial count by capturing bacterial cells, endospores, and viruses as air passes through. These filters have an effective pore size of 0.3 μm, which is small enough to filter out these microorganisms. HEPA filters are commonly used in clinical and laboratory settings to prevent the transmission of airborne microbes.
