"look for your air filter box. its a big square box on the right hand side of the car under the hood. you cant miss it. ther should either be clips or screws holding the box together. you have to get the top off of it to get to the filter... just replace the filter, and put the top back on and ur good"

You have to remove the glove compartment to access the filter. Couple of screws and your done These filters are expensive: 25-30 dollars!
The installation instructions for the Honda Civic DX, LX, and EX s are in the package when you purchase the cabin air filters.
Location of cabin filters: Behind the glove compartment, behind an access door on the passenger side of the vehicle.
To remove existing filters:
1. Open the glove compartment and locate and remove the hindge tabs on both sides of the inside of the glove compartment. The tabs are plastic, and pry out very easily. Once you've pried them open, remove each.
2. Just let the glove compartment door swing down. Note: all the contents will fall out. :-)
3. There is a black plastic horizontal door. Open the door, no tools needed, and remove it.
4. Pull out one filter with its plastic frame.
5.Slide the second filter over, and remove it and its frame.
6. Remove the dirty filters from each frame. (Mine were quite dirty.) And replace with clean filters in each frame.
7. Reinstall both filters and frames into the filter housing.
8. Reattach the filter access door. Tilt the glove compartment door up. Replace the hinge tabs on the inside of the glove compartment.
9. Put all of your staff back in the glove compartment. And you're done!
