<p>A filter assembly including a combination filter element for double filtration of air or other gasses is provided. The combination filter element includes a first filter medium and a second filter medium connected together. The first filter medium has an upstream face, a spaced-apart downstream face, and a plurality of channels extending therebetween. The second filter medium is located adjacent the downstream face. Gases entering the first filter medium through the upstream face flow in the channels and, upon exiting the downstream face, are directed toward the second filter medium. To connect the first and second filter mediums, a connecting band extends about the peripheries of the mediums.</p> |
