cabin filter missing

Arrow goes up on the plastic cover, down on the filter itself. Filters are labeled for direction of air flow.

This is true. If any of you look at an air filter, you'll see a difference in texture and appearance. Air filters that are not just a basic pad of cloth are supposed to be installed a certain way, as they will catch more dust, allergens, and other pollutants. Special HEPA filters meant for a house's air circulation system can catch debris up to half a micron in size, which would include paint and metal vapor.
