B. High Efficiency Particulate Air (HEPA): A HEPA filter is an air filter capable of capturing 99.97% of particles passing through the filter that are 0.3 microns in size and larger.

[E.] Immunocompromised: A condition where a patient’s immune response is reduced or absent. Because defense mechanisms are limited in immunocompromised patients, they are susceptible to infections by microorganisms that are present everywhere, but do not cause disease in healthy people.
