2003 mitsubishi lancer cabin air filter

[cfrank2]

I looked on the wix website and it lists a cabin air filter for this car, where is the filter located? I have seen a tsb released by mitsubishi reguarding debris getting into the evaporator core housing and clogging the drain. It says to add a filter but it dosent say what kind and there is no part number listed. So i assume it is a cabin air filter but i dont know where it is at.

Thanks
