Not sure how big your air filter is or how it is shaped, but I have a couple of ideas for you. When I ran the foam outer on the paper element, I would dry it out by using a paint roller dryer (the kind that spins it). I would fold it in two and stick it where you would put a brush handle in the spinner. Also you can buy one of those salad spinners at a discount store. They are plastic and pretty inexpensive. In the end, I just got tired of the maintaining them and changed my paper more often. I blow them out with an air hose after each off road use, or every 2nd oil change (6,000 miles).
