Can someone please tell me how to get the plastic cover off so that I can change my air filter? The front piece came off easy enough but I have been unable to figure out how to get the back section off to gain access to the filters. I cannot find any metal clips or fasteners holding the back piece on and I have been unable to "snap" it off. Thank you.

 

The rear section lifts straight up and off. You won't see the clips until after you remove the piece...nicely hidden
