How Often Should You Change Air Filter On Car

It is important to change the air filter on your car at least every 12 months or 12000 miles whichever comes first. A lot of people forget to do this simple maintenance task but it is important for the health of your car. The air filter is responsible for keeping the air in your car clean and free of debris. If it gets too dirty it can clog up the engine and cause it to run less efficiently.

Change your air filter more often if you drive in dusty or dirty conditions or if you have a lot of pets in the car. You may also need to change it more often if you have allergies and are sensitive to dust and pollen.

A clogged air filter can also lead to problems with your car’s fuel economy. Your engine has to work harder to suck air through a dirty filter which means it uses more fuel. Replacing a dirty air filter can improve your car’s gas mileage by up to 10%.

So how do you know when it’s time to change the air filter? Most carmakers recommend changing it at least every 12 months or 12000 miles. Some filters can last up to 30000 miles but it depends on the type of filter and the conditions you drive in.

If you’re not sure when to change your air filter consult your car’s owner’s manual. Many newer cars have a indicator light that will come on when it’s time to change the filter.

Changing your air filter is a fairly simple and inexpensive maintenance task. It’s something you can do yourself or you can have a mechanic do it for you.

If you do it yourself you’ll need to know where your air filter is located. It’s usually located in the air intake duct or behind the glove compartment. Consult your owner’s manual for specific instructions.

Before you remove the old air filter take a photo or make a note of the orientation of the filter so you can install the new one the same way. Most filters can be installed in either direction but some have an arrow that shows the correct orientation.

Once you have the old filter out inspect it to see how dirty it is. If it’s caked with dirt and debris it’s time to replace it.

Install the new filter and make sure it’s seated properly. Then close up the air intake duct or glove compartment. Start the engine and check for any leaks.

If you have any questions about changing your air filter or need help finding the right filter for your car contact a local mechanic or auto parts store.
