probably made for Mercedes as it is exact fit. the only improvement would be the [2] metal clips that hold it in place. also a note about the plastic finger that holds cover in place for first time changers.
I'd prob like the product if I wasn't sent a cabin filter that was 3 sizes to big I drive a 2010 Mercedes glk350 and it wasn't even close to being the right size
It's a not charcoal filter. It's as white as paper. It's a paper filter. It's the same size as the original MB filter, but it didn't have the metal clips to hold this filter.
