So at work I bought gold mesh re-usable coffee filters for work. I'm the one that makes the coffee (ugh, don't get me started on this) so I figured I'd substitute something "green" for the regular filters we were using. It takes a little longer to dump/wash out the grounds, but I think it's worth it.
Just in case anyone was wondering about them.

This is what we use at home, too. I actually think it's less messy -- with paper filters, I had several incidents of the paper ripping on the short trip to the garbage can and grounds flying everywhere.
