Well I just finished replacing my cabin filters after a second attempt. Remove the six screws as instructed and then you need to grab the bottom of the door and pull very sharply. I initially used a scew driver and plastic putty knife to try and ease it out.
It didn't work and I disfigured the surrounding dash. I had to take a heat gun ( or hair dryer at VERY low setting )and carefuly kneed the plastic (leatherette)" dash back into place ..a close call but worked great. I used a mirror to locate the scews next to the light on the roof of the glove box and used a small magnet to get them out as they didn't want to drop. I used a 1/4" torque bar with a adapter and no.2 Philips screw head to get the roof screws out
I have decided not to replace the roof screws and may file edge down as recommended. Good luck...it does feel like you will break the door hinges but they seem to be able to take a very forceful pull.
