The Media Air Cleaner Filter in your Lennox S30i system is responsible for trapping airborne particles like dust, pollen, and pet dander, ensuring cleaner air for you and your family. Over time, the filter accumulates these particles and becomes less effective. Replacing it every 6 months helps maintain optimal airflow and indoor air quality. Delaying replacement can lead to reduced performance and potentially even damage to other components in your system.
