It hasn't been officially a year since we purchased our '16 Fwd 2.0 Ecoboost & i was curious about how dirty the cabin air filter was. Mind you, the car is in a garage most of its life & has a little over 12,200 miles. This thing was FILTHY. I mean nearly black.
That looks exactly like the one in my MKX. That's a charcoal filter, it's supposed to look black. One way to tell how dirty it is, after you remove it, hold it up to the sun and look through it. A really dirty filter is difficult to see sunlight through it.
This is the filter I use on my 2009: ATP Automotive FA-14 Carbon Activated Premium Cabin Air Filter https://www.amazon.c...a_rhmVybTZX85QQ
Notice it looks black right out of the box.
I spray the filter with this filter spray to improve its efficiency:

I use this on my furnace filters to improve their efficiency.
