This is the cabin air filter that has been in my daughter's 2013 Ford Edge since (at least) the time we bought it in 2017. For reasons I can't explain, I just never thought the vehicle had a cabin air filter. Fast forward to recently when I stumbled across a YouTube video of someone changing their Edge's cabin air filter. So, today I replaced the old, nasty filter with a new Wix filter. This is what the old cabin air filter looked like at 145k miles. No idea if it was ever changed before we bought the Edge. I'll be changing it regularly going forward.
