Air is an essential requirement for life, but what about when that air contains harmful pathogens? The concept of sanitizing the air is essentially rendering microbes such as viruses, fungi, and bacteria harmless. This can be accomplished in various ways including Ultraviolet Germicidal light, Ozone oxidation, or chemical cleansing such as chlorine. When considering the best way to sanitize the air in a space, it is critical to understand the effectiveness and the risks of the method that is being used.
