2019 RX 350 FWD---CABIN AIR FILTER REPLACEMENT--

[Johneb]

The aftermarket cabin air filter has an arrow pointing to install in "AIR FLOW DIRECTION" . Anybody know which direction the airflow is--upward or downward??

 

Thank you and Merry Christmas !!!!!

Air in this area flows from the top of the filter down to the blower motor and then thru the system.  IOW, the arrow should point down to correspond with the flow of air from top to bottom.

Excellent Stefano--that is the answer I wanted !!!!!!
