When you replace a cabin filter is the airflow generally from top to bottom as you have to put them in a certain way on the filter . In particular this is a 2014 Grand Caravan . The fan is right below the filter so I assume that it sucks the air thru the filter from top to bottom , does this sound correct . Didnt find anything in the owners about how to orient the filter just how to take it out .
