what gen car do you have? I have 7th gen accord and its a piece of cake to get access to the AC filter. Theres a couple of hinges on the left side of the glove box which when disengaged will let the glove box hinge to the floor. Just tinker with it a little bit. After that the only thing you see is the AC filter. Also, order the filter from H&A accessories. They have genuine OEM filters that cost $20-22. I went to Sears just to get the rate, they said $49.99. Good luck!
