Cabin Air Filter Direction Of Airflow

Should it point down like in the picture below which is what i got from the diy b6.

Cabin air filter direction of airflow.

But if the filter has arrows indicating the air flow direction then the arrows have to point down. This side up is simple as can be. If you take out the installed filter the dirty side is on top so that implies that the airflow is down. Hence look at the label of the new filter and see whether the arrow is for airflow or just direction and install accordingly.

Looks like the air flows downward because my old filter had all the dirt on the top side of the filter. Every other thread on the air filter is filled with people stating to install the arrow pointing down. The toyota filters being for specific case can use the tsu label aftermarket not so much. The oem filter has direction arrows pointing up.

Airflow direction requires waay to much sleuthing. This makes sense as the air is drawn in from the base of the windshield through the filter and to the fan. I might just change the cabin and engine air filters on ours it s coming up on 10 years this fall. If the air filter has arrows that say this side up then the arrows should point up.

If you install your filter in the wrong direction air will have a hard time flowing through the filter s material and your air handler will have to work overtime to make up for the loss of airflow. Ok here is a stupid question and yes i know this is only 1 wrench if that. Cabin air filter i have a 2010 camry.
