Cabin Air Filter Direction Of Airflow

I might just change the cabin and engine air filters on ours it s coming up on 10 years this fall.

Cabin air filter direction of airflow.

Every other thread on the air filter is filled with people stating to install the arrow pointing down. The thing that i have is which way is the direction of the air flow or should the arrow point. Cabin air filter i have a 2010 camry. The oem filter has direction arrows pointing up.

But if the filter has arrows indicating the air flow direction then the arrows have to point 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. The toyota filters being for specific case can use the tsu label aftermarket not so much.

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

Ok here is a stupid question and yes i know this is only 1 wrench if that. If the air filter has arrows that say this side up then the arrows should point up. This is not only a waste of energy but it can also possibly damage your air conditioner.
