Hello everyone,

Can someone please tell me how many pollen filters are in a W140 WITHOUT the activated charcoal feature?

Thanks!
Bryan

There's a filter above the blower motor (engine bay inboard of right hood hinge, and a filter in the cabin in the lower dash cover in the passenger footwell.

Thanks sixto . . . I just finally figured this out right before you posted

I kow how to replace the one above the blower motor, but I don't know how to erplace the other in the passenger footwell . . . do you have to remove the glovebox or anything like that?

regards,
Bryan

There's a flap along the bottom of the dash in the passenger footwell.

1 Turn latches on recirculating air filter housing in passenger foot well 90° counterclockwise (open). To close during Installation, turn 90° clockwise.

2 Remove cover with recirculating air filter towards bottom.

3 Open recirculating air housing.

4 Remove recirculating air filter.

5 Installation is in the reverse sequence.

Awesome! Thanks Sixto!

I thought that changing this filter was done inside the engine bay . . . it sounds super easy to change!

I would have taken a look at it myself, but the car is at my parents' house two hours away. I am going home tonight to change there filters, and wanted to know how before I went there.

Thanks once again!

There's a filter over the blower for outside air and a filter in the cabin for recirculated air. The activated charcoal filter is something else entirely.

Yeah . . . I think you are referring to the pollen filter. I have purchased one of those as well, and am going to replace it tonight.
