What is the main role of filters in the HVAC system?

The primary role of filters in an HVAC (Heating, Ventilation, and Air Conditioning) system is to clean and purify the supplied air. Filters capture dust, pollen, and other airborne particles, which helps to maintain indoor air quality. By removing these contaminants, filters protect the HVAC system components from damage and reduce the accumulation of dust in the living or working spaces, leading to a healthier environment.

Additionally, clean filters can improve the energy efficiency of the system, as they allow for better airflow and reduce the load on the heating and cooling components. This aspect emphasizes the importance of regular filter maintenance and replacement, which is critical for optimal HVAC performance.
