Cabin air filters for your car

What to check before you buy

• Your owner's manual shows where the filter sits and how often to change it.
• Match the filter to your car's year, make and model before you buy.
• A particulate filter traps dust and pollen; an activated carbon filter also absorbs odors from outside.
• Before you take the old filter out, note which way the airflow arrow on its edge points.

How to use it

1. Park on a flat surface, set the parking brake and open the glove box.
2. Empty the glove box, then lower or remove it to reach the filter cover.
3. Open the cover, note the airflow arrow and pull out the old filter.
4. Slide in the new filter with the arrow the same way, close the cover and refit the glove box.

Good to know

• A cabin air filter cleans the outside air that the heating and air conditioning blow into the car, catching dust, pollen and other debris.^1,2,3,4,5
• It is not the engine air filter: the engine air filter cleans the air the engine burns, while the cabin air filter cleans the air for the people inside.^4,6,7
• On most cars the filter sits behind the glove box; on some it is reached from under the hood. Your owner's manual shows where yours is.^3,8,9,10
• Your owner's manual gives the replacement interval for your car, and driving on dusty roads or in polluted air can mean changing the filter sooner.^1,3,4,7,11
• Several carmakers, filter makers and parts stores advise changing the cabin air filter at least once a year; the mileage they give differs from one source to another, so go by your owner's manual.^1,2,3,10
• Common signs of a clogged filter are weak airflow from the vents, a musty smell when the heat or air conditioning runs, and windows that fog up and are hard to clear.^2,6,9,12
• There are two main types: particulate filters, which trap dust and pollen, and activated carbon (charcoal) filters, which add a carbon layer that also absorbs odors.^2,4,5,13
• Changing it is usually a quick do-it-yourself job; put the new filter in with its airflow arrow pointing the same way as on the old one.^{3,6,9,11,12,14}
