To be considered medical grade, what must air be subjected to?

For air to be considered medical grade, it must undergo filtration. This process is crucial because medical grade air must be free from contaminants, including dust, allergens, and microorganisms, which could harm patients, especially those in critical care or surgical settings. Filtration ensures that the air meets strict purity requirements, making it safe for respiratory therapy, anesthesia, and other medical applications where air quality directly impacts patient safety and outcomes.

The necessity for high standards in air quality is reflected in regulatory guidelines that dictate how medical air should be processed and maintained, thus emphasizing the significance of filtration in achieving those standards.
