Daft question but the airflow direction for the pollen filter is from left to right I assume!!?. Glove box to centre console?? Took my filter out to do an anti-bac and it's in the wrong way ie flow direction arrow going away from centre console and there is all debris on the supposed clean side so turning it around will let the shat fly around the car!
I do wonder why some people mess if they ain't sure. Grrr new one i guess now then.
