How to Change Air Filters in a Car – What You Need to Know

Learning how to change air filters in a car might not be your idea of fun, but it can be an excellent way to save money. It’s usually easy, though some car brands may make it a bit more challenging.

Typically, when you get the oil changed in your vehicle, you have to option of changing the air filter. You may think it’s part of the deal, but it can sometimes cost just as much as the oil change to finish it.

The air filter itself is quite inexpensive. Your mechanic or quick-lube shop charges you much more because of the labor involved. Most people believe that it’s complicated to change their air filters and requires special tools, but that’s not the case!

In fact, changing an air filter in the car is probably the simplest and easiest maintenance task you can do yourself. It takes a minute to do and doesn’t require special tools. You just need to know how to do it, and this guide can help!


What Your Air Filter Does

Engines need air to run. The air ends up mixing with the gas, gives the spark plug the spark, and you’ve got combustion. For the engine to run smoothly, the air should be clean as it goes inside. However, outside air is full of bad things like salt, pollen, bird feathers, and dirt. That stuff can’t go inside the engine, so the filter removes them.


Typically, the air filters are connected to the intake manifold and are rectangular. They’re often made to look like an accordion and feature paper-like material. This filter keeps particles from getting into the engine and letting clean air inside.


Why Change the Air Filter Regularly

There are many reasons to change your car’s air filter, such as:

  • Reduced Emissions – When there’s reduced airflow, it can mess up the emission control systems. That means you’re putting out more bad things into the air.
  • Prolong the Engine Life – Engines are powerful, but they’re quite sensitive to dust and dirt. With time, those particles can cause significant damage to the internal components of the engine. It’s always better to spend a few dollars now to get a new air filter than thousands of dollars for a new engine.
  • Better Fuel Efficiency – After many thousands of miles on the car, your air filter can get clogged. That means less air can get to the engine. All engines require air to work correctly, so any reduction in airflow means you’re using more fuel to run the same motor. Save money now and change the air filter regularly.

How Often to Change the Air Filter

Most mechanics recommend people change their air filters once a year or every 12,000 miles. Those who live in dusty locations may want to do this more frequently. Typically, it’s a good idea to check the air filter whenever you get an oil change. The mechanic automatically does that for you, and when they say it’s time for a new one, say you’re going to wait. Then, you can do it yourself and save a lot of money!
