I have this problem on my air filter, a friend told be to follow this video on how to replace cabin air filter, i dont think this applies to my car, i have a getz.. any advice?

 

I don't know exactly where the filter is on the Getz but the majority of Hyundai vehicles have the cabin air filter located behind the glove box. That where it is on the Accent, Elantra, Tiburon, Tucson, Entourage, etc.

Basically remove the the glove box, remove the door to the filter and slide the filter out.
