There are SEVEN phillips head screws holding the glove box assembly, and that glove box is covering up the Cabin Air Filter. FIVE of the screws are exposed by opening the glove box.
The other TWO screws are found underneath the glove box assembly. This photo shows the bottom left corner of the glove box door, highlighted with the arrow, and the screw is circled.
The bottom right corner of the glove box door is indicated in this photo with the arrow. As you can see, the phillips head screw is holding more than just the glove box. It is also holding part of the dashboard cover, and I consider the entire thing the "glove box assembly" to include both the glove box and this part of the dashboard.
After removing the SEVEN screws, the dashboard assembly needs to be flexed so it will unhook from both above and below. Wiggle it around and you will figure it out. The next photo shows the fan housing and cabin air filter WITHOUT the glove box assembly in place.
The cover for the cabin air filter is now exposed and can be removed by unclipping two snaps at the bottom and unhooking it from the two top hooks. The cover plate has been outlined in red to help identify it, and the two bottom snaps are indicated with the arrows. Notice that there is a wiring harness in the way on the right side. It makes removal/replacement of the filter just a little bit difficult.
This is a close up of the filter cover plate. Again the cover is circled in red and the snaps at the bottom are indicate with arrows, but the two hooks at the top are also identified here. Pull the bottom of the two bottom snaps back toward yourself to unsnap them, then wiggle the cover plate and you will see how it comes loose from the upper hooks.
In this final photo you can see the rear edge of the cabin air filter cartridge. It simply slides out when you pull on it. Push the wiring harness on the right out of the way to get the cartridge out. Notice that there is an "UP" indicator on the edge of this filter cartridge. Don't get that confused with the direction of air flow, which is actually DOWN. When you take out the old filter you will see that all of the dirt is on TOP of the filter cartridge, so it is obvious which way the air is flowing.
