This is particularly important when air quality is poor, as it is during our current state of emergency. It's important for everyone to be breathing clean air in their vehicles, but most especially for sensitive groups, seniors, those with lung or breathing difficulties, and children.
Every vehicle has an engine air filter that cleans the air going into the engine, but not all have a cabin air filter that cleans the air going into the passenger compartment.
The cabin air filter cleans out dust, pollen, spores and other pollutants. To give a point of comparison, a grain of sand is about 200 microns across. A cabin air filter can stop particles that are just 3 microns in size. It really does make the vehicle passenger cabin a much more pleasant environment.
When the cabin air filter gets dirty, drivers just need to replace it. Your owner’s manual may have a recommended interval for changing it. If not, we can inspect it at the shop and give you a recommendation. It’s ironic that many people who don’t realize they even have a cabin air filter first find out they do when it starts to get smelly.
Some vehicle cabin air filters are very easy to access when it’s time to replace them. Others, not so much. Your service advisor may have to get behind the dashboard and it takes some time.
A clean cabin air filter keeps out smog, allergens and other harmful pollutants. If it’s time, get it changed right away.
