Here is a Mann filter ML1010 that is atleast 11 years old.
Per my other post as promised - here is the cut open of the filter.
We often times question if we can use an old filter but don't often use data to make these decisions so I cut this one open. My opinion is that it was still good to use! The rubber parts were still soft/pliable and the media (my biggest concern) was still solid and didn't crumble away when trying to break the pleats.
