Abstract
A refrigerator incorporates an air filter for filtering an airflow passing along at least one refrigeration component into surrounding spaces. The air filter is positioned in an upper machine compartment which houses refrigeration components associated with maintaining temperatures in the refrigerator. At least one sensor is arranged adjacent the air filter to determine a parameter of the air flow. A control, including an air filter analyzer, determines a need for an air filter change based on the sensed parameter. In addition to removing impurities from the airflow, the air filter includes scented media which adds fragrance to the airflow.
