<prompt> Sepheo sa sefe ea moea tsamaisong ea HVAC ke eng?nan  <response>: Instruction in English: What is the purpose of an air filter in an HVAC system? . Response in English: An air filter is an essential component of an HVAC Heating, Ventilation, and Air Conditioning system. Its primary purpose is to clean the air that circulates through the system by trapping airborne particles such as dust, pollen, pet dander, and other pollutants. This not only helps improve the overall indoor air quality, but also protects the HVAC system itself by preventing the accumulation of dirt and debris that can reduce its efficiency and cause damage to the components over time. Regular replacement or cleaning of the air filter is crucial in maintaining the performance and longevity of the HVAC system, as well as promoting a clean and healthy indoor environment. .
