Funny, element looks like a roll of toilet paper. It is a very tight roll and has the ability to absorb a lot of moisture. I have used it now for about 6 months now and not one drop of water has left the filter(that I know of). One thing is if I am not going to use my air for a few days I open the canister and let it dry out. It seems some people have had trouble with white corrosion developing in the aluminum housing.
