Cabin Air Filter Direction Of Airflow

If you take out the installed filter the dirty side is on top so that implies that the airflow is down.

Cabin air filter direction of airflow.

Looks like the air flows downward because my old filter had all the dirt on the top side of the filter. Hence look at the label of the new filter and see whether the arrow is for airflow or just direction and install accordingly. The oem filter has direction arrows pointing up. The thing that i have is which way is the direction of the air flow or should the arrow point.

Should it point down like in the picture below which is what i got from the diy b6. But if the filter has arrows indicating the air flow direction then the arrows have to point down. This is not only a waste of energy but it can also possibly damage your air conditioner. Cabin air filter i have a 2010 camry.

Every other thread on the air filter is filled with people stating to install the arrow pointing down. 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. This makes sense as the air is drawn in from the base of the windshield through the filter and to the fan. This side up is simple as can be.

Airflow direction requires waay to much sleuthing. Ok here is a stupid question and yes i know this is only 1 wrench if that. I might just change the cabin and engine air filters on ours it s coming up on 10 years this fall.
