Craftsman 3.7/18 air filter

I know parts for this saw are difficult to find, but I am in need of some type of air filter that will work with it. Does anyone have any ideas as to where I could find one, find something similar, or fashion something that will prevent foreign matter from getting in my carb.? TIA..

Photo of the old filter with dimensions would help.

It did not have one when I got it, but I found a picture of one online a few days ago.. I will try to find it again and will post pics of that and the air intake on the saw. Ty
