Heating and cooling systems use an air filter to clean the air before it is conditioned and circulated throughout the home. This filter has two main functions: to protect the HVAC system from dust and other particles that can cause component wear, and to remove dust, pollen, pet dander, and other pollutants from the air, which can improve indoor air quality and reduce symptoms of conditions such as asthma and allergies. Some air filters are designed to protect the HVAC system only, while others can both protect the system and improve air quality.
