Many car manufacturers, including Hyundai, install a HEPA filter, commonly called a cabin air filter, in the inside air intake of the car. This filter removes allergens and other particles from the air before it enters the vehicle's passenger compartment. Replacement of the cabin air filter keeps the air you breathe inside your Hyundai clean and allergen free. This maintenance project can be completed by the home mechanic in just a few minutes, using basic hand tools.
Remove the Phillips-head screws and the 10mm bolts that attach the glove box insert to the dash. Pull the release tabs on the glove box door travel stops and release the glove box door from the glove box. Slide the glove box insert out. Remove the lower dash trim panel on the passenger side of the dashboard.
Remove the old HEPA filter by depressing the locking tabs on the filter cover located on the front of the plastic evaporator case located directly behind the glove box. Then slide the filter carefully, out and down, to prevent knocking the dust that has been captured by the filter into the evaporator case or onto the carpet.
Install the new filter by sliding the new filter into the evaporator case. The new filter is labeled to indicate the direction it should be installed into the evaporator. Push it completely into the case, and close the cover until the latches snap into place.
Reinstall the glove box insert and attach it to the dashboard using the original screws and bolts. Insert the door travel stops into their slots and push the door closed. The stops will automatically snap into place. Reinstall the lower dashboard trim to complete the project.
