1. Have tools handy, if necessary

You may want to have your toolbox handy in case you need a screwdriver or socket set, but most of the time, you can inspect and install a new filter without any tools, according to The News Wheel. Cover up the passenger side floor mat if you're concerned about dust and dirt getting onto the floor of your car.

2. Remove the glove box

For most makes and models, you'll have to remove the glove box to gain access to the cabin air filter. If you don't know how to do this, you can check your owner's manual for instructions, says AutoZone. You might need a screwdriver for some vehicles, but AutoZone notes that removing the glove box is often just a matter of pressing a couple buttons. If your vehicle doesn't require that you remove the glove box, the owner's manual will provide information on the location of the cabin air filter.

3. Locate the air filter

When you locate the cabin air filter, you should note how it sits, so you understand how to put the new filter in properly, explains The News Wheel. Gently take it out, along with any other debris that might have collected in the space.

4. Clean the area and install the new filter

Vacuum the area thoroughly to remove any other dirt before putting in the new filter, recommends The News Wheel. The new filter will likely have arrows on it to indicate the correct airflow direction.

5. Replace the glove box

When you're finished, replace the glove box. Now that the job's done, you can enjoy cleaner air in the car cabin for you and your passengers — and savor the fact that you likely saved yourself money by doing it yourself.
