You can look in your vehicle 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. You can also ask your friendly and knowledgeable service advisor at Advantage Tire Wheel & accessories in Slidell.
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 vehicle engine compartment or under the dashboard.
Because cabin air filters are so new on the scene, some Slidell motorists haven't heard of them – even people who have cabin air filters. Advantage Tire Wheel & accessories service advisors report customers complaining of an unpleasant odor in their vehicle and it turned out to be a dirty cabin air filter.
An important note for Slidell hybrid owners: there is a special air filter that cleans the air that cools the hybrid battery pack. This filter should be inspected every time the cabin air filter is inspected and replaced if it is dirty so that the battery pack doesn't overheat.
