  1. It is rather disturbing that we are not hearing about the importance of cleaning hybrid battery filters from other sources. I never knew until you told us about them. When I looked at the one in our 2014 Prius I thought, "good - the filter does not have much dirt on the fiber mat." When I watched your video I understood there is no fiber mat - it was a mat of dog hair! You also gave us the number of the external filter that is a snap to clean.
