Air quality affects us wherever we are. Many decades ago, residents began to become aware of how air pollution negatively affects health. But what about the air inside your vehicle?

Cabin air filters are now coming on most new vehicles since the 2000 model year. These filters clean the air in the passenger compartment. They can filter particles down to three microns, so that’s good enough to clean out dust, pollen and most pollutants. If you suffer from allergies, this is very good news.

You can look in your owner’s manual to see if you have a cabin air filter. If you do, there’ll be a recommendation for replacing it when it gets dirty. If you live where there’s a lot of dust, pollen or pollution, you may need to change it more often.

How hard it is to change a cabin air filter depends on your vehicle. Some are quite accessible; others take some doing to get to them. They’re usually in the engine compartment or under the dashboard.

Because cabin air filters are so new on the scene, some  motorists haven’t heard of them – even people who have cabin air filters.
