The correct term for the process of removing contaminants from indoor air is air purification. Air purification encompasses various technologies and methods that aim to improve indoor air quality by eliminating pollutants, allergens, and harmful particles from the air. This can include the use of air purifiers, HEPA filters, and other filtration systems that specifically target airborne contaminants.

Understanding the nuances between this term and others in the context of indoor air quality improvement is important. For instance, air filtration refers specifically to the mechanical process of trapping particles, while ventilation describes the movement of outdoor air into an indoor space to dilute and replace indoor air. Air clean-up is not a widely recognized term in this context and does not accurately represent the specific actions taken to improve air quality. This distinction is crucial for anyone studying commercial mechanical systems and looking to maintain healthy indoor environments.
