Review on EPAuto CP388 (CF10388) Cabin Air Filter with Activated Carbon - Premium Replacement for Nissan/Infiniti by Dave Russell

They installed it exactly as it should and the problem isn't with the filters, it's that NISSAN made the dashboard so damn layered in the 2006 Armada. Both filters are inserted next to each other and that's it. The ONLY thing I have to complain about is that the filters are not clearly labeled which side is up (direction of airflow). I had to look at an old filter made of a similar material and guess from two different colors. I put a slightly lighter white side up, but I'm still not 100% sure if that's correct or if it makes a difference. It would be nice to have a label, especially since the packaging says it should be used ;) It's just that it doesn't say it on the filters.
