Changing your cabin air filter
Most of newer cars have a cabin air or pollen filter that filters outside air coming into the cabin. A cabin air filter is recommended to be replaced every 12 months or 10,000-15,000 miles (16,000 - 24,000 km).
Signs of clogged up cabin air filter include reduced air flow and bad odor coming from the air vents.
A cabin air filter clogs up faster if your car is parked under trees or if you drive on unpaved roads.
Some manufacturers post the instructions how to replace the cabin filter in the owner's manual, others recommend visiting a dealer. In some cars a cabin filter is very easy to replace, in others, you will save a lot of time if you have a dealer to do it.
If you want to better filter out odors, you can buy an activated charcoal cabin air filter that better absorbs various smells. We tried, it does make a difference.
Where is the cabin filter located?
Where is the cabin filter located in your car? It would be great if all car manufacturers would figure out a universal placement for a cabin filter, but they haven't.
