I've been running their intakes for three years now. I got a set of the black hex filters that I purchased when they released them a while back (maybe ~1 year?).

FWIW, I've never felt like blowing air in/on them cleaned them out very well. So I always wash them in a bucket of water with some Simple Green. Since I now have two sets, I can let them air dry for several days before storing them.
