What is the purpose of air filtration in HVAC systems?

Air filtration in HVAC systems is primarily aimed at enhancing indoor air quality. This is achieved by removing particulate matter such as dust, pollen, mold spores, and other pollutants from the air that circulates within a building. Effective air filtration systems trap these contaminants, preventing them from being recirculated into living or working spaces, thereby reducing the potential for respiratory issues and allergies among occupants.

Good indoor air quality is essential not only for health and comfort but also for overall well-being. By capturing harmful particles, air filters contribute significantly to a healthier indoor environment.

While aspects like managing humidity levels, improving energy efficiency, and reducing noise can be relevant in HVAC systems, they do not primarily relate to the main function of air filtration. This differentiation helps clarify the specific role of filters in promoting cleaner air for occupants.
