Cabin Air Filter Replacement
For the cabin filter, you have to go into the passenger footwell. Fold down the carpeting and there is a cover with two clips that open up towards you, then the cover pulls out. The filter is in there, it's a tight squeeze but it will pull out and the new one slides back in the same way.

I live on the coast away from a lot of pollution and dust though so expect mileage to vary.
I was impressed with the German engineering under the hood to replace that filter...quarter turn fasteners, very cool. In the footwell, not so much...not convenient at all...

1. After unscrewing the bottom glovebox lid, you have to be prepared to pull and wiggle as it just doesn't drop down
2. Once the filter's clip is removed, the filter doesn't just drop out (at leas mine didn't.) On the left, there is a space between the filter and its housing. Put your finger in there against the side of the filter and pull and jiggle. The filter will come out.
3. To remove the plugs on the inside of the lid, you may have to pull forceably on the one on the left and you will have to depress the top of the one on the right as you pull
4. Because the space between the bottom of the fliter's housing and the car's floor is less than the length of the filter you will have to be prepared to deform the filter a little as you push it in.
5. I was unsuccessful in replacing the lid. I just couldn't maneuver it so that it would fit in. It's been suggested that you first try to engage the right rear of the lid into it place, but I couldn't do it. Certainly would appreciate some more detail on how to do it.
there are two pieces to the filter cover. The lid itself, and this sliding piece thats attached to it. if you're holding onto the two pieces together, and you slide the "sliding piece" to the right, you sort of lock it into place. What confused me was that I thought I had to put the lid / cover back on and then slide the sliding piece to the right, to lock it in place. however, what you have to do is (before putting the cover back on) have the sliding piece slid to the right, so that it's "locked in," and while its "locked-in," place the cover over the air filter, and then slide the "sliding piece" to the left to secure it. I hope that made sense.
Or, you can raise the plastic up enough to unhook the filter housing without removing it from the windshield side at all, I've seen many techs do it that way. Once you know how the dust filter holder releases, it comes out pretty quick.

I often have to slide under there with a flashlight to line the filter cover back up, due to the strange design it has, and make sure the rubber gasket of it sits in the channel on the inner end properly so you can engage the latch easily. Still better than the 204/212 design with the very difficult slider and no real alignment to speak of, but nothing like the CLA/GLA with just two simple clips and no panel covering the filter. The S class has two filters in a V shape, makes it even more tedious to fit them then the lid back in place, plus the lid has screws in addition to sliders.
