The main types of microorganisms relevant in air filtration include viruses, bacteria, and fungi. These microorganisms are significant in the context of air quality and health because they can be airborne and have the potential to cause diseases or allergic reactions in humans.

Viruses can be spread through the air, particularly in enclosed spaces, and they can lead to various health issues ranging from mild illnesses to severe diseases. Bacteria can also be present in the air, and like viruses, they can be pathogenic, contributing to respiratory infections and other health problems. Fungi, including mold spores, are another critical aspect as they can grow in humid environments and release spores into the air, which can cause allergic reactions and respiratory issues.

This answer encompasses the most relevant microorganisms associated with health concerns in the context of air filtration. Other options might include microorganisms that are less significant or relevant to the air filtration process, thereby making them less accurate in identifying the main types of microorganisms of concern in this field.
