I just removed my in-cabin filter and it looked upside down meaning if you read the nissan on it,it was upside down but the arrow was pointing down which is the way the airflow is moving,so i replaced w/puralator and writing is also upside but the arrow is also pointing down.has anyone else come across this issue? I was told by infinity arrow needs to be down but damn just confuse us all i guess!!

 

filter is a filer... if it fits, it will work

 

it should point down since it draws air down...the filters are all the same...the charcoal doesnt filter any better

 

If anything, u should complain that the new Nissan filters don't come with the sticky back.

 

the new filters @ the dealer don't even say nissan on them anymore. For that matter, there's no writing on them what so ever. Doesn't matter which way you put it in.
