Wow. I just had a creepy experience while doing some maintenance. We've got some nice 4U chassis that are probably near 15 years old now, still great for many uses. They've got a washable fan filter in them that needs to be removed every year or two and rinsed, dried, and reinstalled, or else the airflow becomes reduced. The filter is basically extremely low density foam of the kind that is very soft. We wash them out with plain water, crumple them up to squeeze them out, let them dry, and reinstall.
Now bear in mind these have been undergoing the process for many years without incident. So imagine my surprise when I took one out and my thumb went right through it. It was still flexible but it seemed to tear very easily. I put it under the water and it just totally disintegrated.
I have no idea what would have caused this; the filter in the next server up was just fine.
