Read the entire thread carefully.
If there are no factory installed air filters, then the box is sealed, just like you found it.
There are no hidden filters enclosed inside.
You can install filters, but first you have to cut the slots open in the black box (see pics in other posts in this thread).
It's actually quite simple (I've done it), and the filters slide in nice and easy.
