Just
followed this DIY and replaced my original cabin air filter with a Fram Fresh Breeze CF 10549. I have pretty bad seasonal allergies so I went with the Fram vs OEM because it's carbon activated and has baking soda to kill odors. The Fram is also significantly heavier so that tells me the filter element is more dense and will do a better job filtering.
The stock one was pretty dirty and had a bunch of leaves and crap in it with 11k miles and 100% garage storage. Will report back later if I notice any odor neutralization.
