A filter element generally follows the oscillating shape of the frame elements. An air filter system is also disclosed. The air filter system can include the air filter and an air filter container. The air filter container contains the air filter and directs air through the air filter in a predetermined direction. An air filter is disclosed including a support structure and an oscillating shaped filter element attached to the support structure.
