YOu have to remove the cover at top of passenger footwell (if I recall its t15 or t20 torx screws) After you do that you will have access to the FILTERS. On my Maybach there are TWO I suspect your car is the same. Look on places like Autohaus for the filters.
To remove the filter cover there is a WHITE slide lock mechanism you slide one way to release and there is at least one more screw you have to remove on the same cover. You can then get the filters out. Make sure you put the new ones in for the correct air flow which you can learn by looking at how the old filters slide out.

thanks for sharing.
I believe there are two different part number from Mercedes:
A2228300318: For the car without P21 Air Quality Package
A2228300418: For the car with P21 Air Quality Package
2016 S550 sport, 2018 GLC300, M3, Zo7, 2021 Sierra Denali
I used similar ones to what Katie recommended. They work and fit perfect and not any issue at all in over 10, 000 miles. It's just a cabin filter. Certain items I only use OEM but in this case not. Not a hard job, but definitely a little bit of a pain only due to I am not a contortionist!

S class is easy
While the filter is up there and perhaps a bit challenging to get at IT Ain’t nothing compared to changing the filter on the AMg GTC. That car has a deep small footwell and the filter is in the same place. It is a 100 cuss word job only because you can only Stand lieing on your back briefly across a four inch door sill with little room to move.

I tried to remove the lower panel that covers the cabin air filters on my 2020 W222, S560V, but after removing the three tore screws, there are two clip-like devices (or friction snaps?) that prevent me from pulling down that panel. Are these to be simply forced downward or do I need to apply a particular technique or lever-type action, such as with a flat screwdriver?

On the filter housing? The 2 white clips slide as outlined in the posted video. Good Luck..
Nice Ride, no I can’t drop the first panel down to get access to the filters. Removed the three screws but there is something preventing me from lowering the panel at the far left & right sides…as if there is a hidden catch that must be released in order for the panel to be lowered. Is there a certain force that I must apply…by twisting, pulling or pushing against the panel once the screws are removed?

Good luck orienting the new filters in the correct position. The Mercedes-branded filters that were in my car did not have any markings, so the only thing that gave a clue to how to install the new ones were 'flaps' on either end of the filters. Unfortunately, by the time I figured this out and posted on here, I could not recall how the flaps were oriented on the old ones. The picture is of my old filters in what appears to be one of two possible positions of the flaps.
If your replacements have air flow arrows as mine did, the arrows are supposed to "point toward the blower motor(s)" ... but I've not been able to figure out where the blower motor is relative to the filters.

The blower motor pulls from the outside of the "V". The inlet air hits the inside of the V. In some applications the pins that go into those holes on the top only fit one way, but the best option is to match the way it comes out, if the filter isn't marked.
Thanks ItalianJoe, now that I know the arrows/airflow on the filters should point to the outside of the V, I can go make sure they're in there correctly.
Just a quick follow-up. There was no issue in removing the cabin filter access panel under the glovebox on my ‘20 S560. I just had to do some pushing and pulling to get it to come off once I’d removed the three retaining screws. But…once that panel was removed, I did find two small torx #20 screws that held the plastic cover panel covering the cabin filters. Removing one of them…the screw closest to the console…was difficult because there was no room next to the console kick panel to place my screwdriver into the necessary vertical position. I had to use a small pair of locking pliers to hold the torx bit and then make tiny rotations to get that @#&$! screw off.
What I needed to do was either remove the obstructing kick panel (I have no idea how) or get a flexible bit adapter for my screwdriver, which unfortunately I didn’t own at the time.

Has anyone verified that this is correct? The arrows, as the filters manufacturers state, is the air flow direction (direction the air is flowing towards). This post states that the air flow direction flows towards the blower motor. Thats not possible. The blower motor blows air out towards & into the V (stick your hand or a napkin up there if you don't believe me). The arrows on the filters should be facing each other, not away from each other. Please, an expert, correct me if I'm wrong?
I get that the MB directions state to point the arrows towards the blower motor. Maybe that's for the OEM MB cabin filters. But that's not what the after market (non OEM) cabin filter manufacturers state (arrows point towards the air flow direction).

Right, as you said, the air coming into the filters is inside the "V", so the airflow direction is from the inside to the outside of the V, so the arrows point accordingly. Yes some things say arrows towards the blower, but I don't think that applies in this application.

Are you saying that the arrows need pointed away from each other, towards the blower motors (against the direction of the air flow)? Or arrows point towards each other (in the direction of the air flow)? Please specify the direction of the arrows.
