Cold Air Return?

i assumed the grill in the (interior) steps of our 340RL was the cold air return for the furnace, but i wasn't expecting a wide open hole into the pass-thru. Right now i have some 12" w furnace filters cut down, but want build something a little more ... resistant? Anything that flies, crawls or hops into the crawl space now has a wide-open path to the space my wife would rather that they didn't. Any ideas?

You can get this type of decorative material at Hobby Lobby stores. That is what I used to make my stairwell covers. Easy fit with just a little trimming.
