30MM Fan Air Filter

This device helps keep hair spray, dust and other contaminants out of your fan. The filter media is larger than the 30MM fan to provide more filter surface area and less air flow restriction, even as it begins filling up.

This air filter housing slips over your 30MM Fan, requiring no tools or screws. It DOES require you to purchase a piece of aquarium poly filter element, approximately 1/4 inch or 4-5MM thick, available from your local aquarium store. Cut the poly to 43MM x 49MM with scissors
