What is the name of this part ?

Recently I went on a trip and left my car sitting outside. When I came back I discovered a mouse had gotten in and ate some crumbs left by some messy passengers. The mouse came in through the cabin air filter system and chewed it’s way through a small piece of fabric separating the filter from the cabin. I looked for this part for about an hour online with no luck, but I was wondering if anyone else knows what’s it’s part number is or where to find it. I attached some photos below of where it came from and the piece of fabric.
