Cabin Air Filter Direction Of Airflow

Cabin air filter i have a 2010 camry.

Cabin air filter direction of airflow.

This is not only a waste of energy but it can also possibly damage your air conditioner. The thing that i have is which way is the direction of the air flow or should the arrow point. 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.

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. The toyota filters being for specific case can use the tsu label aftermarket not so much. Hence look at the label of the new filter and see whether the arrow is for airflow or just direction and install accordingly.

Every other thread on the air filter is filled with people stating to install the arrow pointing down. Ok here is a stupid question and yes i know this is only 1 wrench if that. Should it point down like in the picture below which is what i got from the diy b6. This side up is simple as can be.

However i was outside replacing my cabin air filter today and when i opened it up it was really dirty and had a crap load of debrees in there. I might just change the cabin and engine air filters on ours it s coming up on 10 years this fall. If you take out the installed filter the dirty side is on top so that implies that the airflow is down.
