Abstract

An air filter comprises a filter element that includes a proximal surface configured to receive a flow of air; is configured to remove a set of pollutants from the received flow of air; and includes a distal surface configured to allow passage of the flow of air after removal of the set of pollutants. The air filter further comprises a first activation element that is in contact with a first activated area located on the proximal surface of the filter element; and is configured to activate the first activated area; and also comprises a second activation element that is in contact with a second activated area located on the distal surface of the filter element; and is configured to activate the second activated area. In some embodiments, the air filter further comprises a controller configured to independently control operations of the first activation element and the second activation element.
