Thank you for posting this. Due to the wildfires and smoke in Western Oregon this week, our Air Quality Index is the worst in the entire world. With my daughter having asthma, I was looking to change her cabin air filter in her 2012 Malibu LT, only to find she doesn't have one. This forum showed me how to install one. I could not find a CF10361, so I just used a tape measure to find the dimensions of the slot and then started measuring every cabin filter in Autozone that looked close. Found the CAF1813P fit. She is driving to work, about an hour away and reports that she cannot smell smoke in the car and her asthma is not bothering her at all.
