Cabin filter OEM Toyota or OEM Volkswagen

There should be a mesh screen on the passenger side of the car, under the raintray. Other than catching leaves, it's pretty worthless. I installed a mk4 cabin filter in mine. It's a direct swap and the filter catches any dust, pollen, etc.

lol i did the cabin air filter, and i also threw in a dryer sheet and now my car smells like fresh dried laundry... HAHA!!!! seriously though it smells really good.. and i only gotta change the sheet about once every other week.....

I change my cabin filter every 20k or so. Otherwise it'll start to smell like feet/white chadder popcorn/eggs.

Note that changing your cabin air filter could help too.

Mk7 GTI, currently at 5k miles but strong mildew smell coming from the vents.. I know the cabin air filters will last at least 15-20k miles. Anyone have a similar issue?
