How often to Replace Car Air Filter – [Explained]

It is easy to overlook replacing the engine air filter, but a dirty air filter can negatively impact the performance of your car.

The modern car usually has two air filters: one for the cabin and one for the engine. Cabin air filters also need to be changed periodically, but the schedule is different from the engine air filters. A well-designed engine air filter keeps dust, dirt, and other environmental contaminants out of the engine. In time, the air filter becomes clogged and dirty, and it needs to be replaced.

Air Filter Change Car

Engine air filters need to be replaced on a regular basis. Different vehicle manufacturers have different maintenance schedules regarding how often to change the air filter.

Chevrolet engines, for example, should be changed every 45,000 miles, but Ford recommends doing so every 30,000 miles. For severe driving conditions, such as heavy traffic in hot weather and frequent driving on unpaved roads or dusty roads, Hyundai says every 15,000 miles, rather than every 30,000 miles.

All makes will be subject to the same rule. Those conditions require you to replace the air filter sooner if you drive in them.

Simply looking at a filter can tell you whether or not it needs to be replaced. When the section through which outside air enters has black areas, it may be time for a change. If you need help finding the location of the air filter, check your owner’s manual.

When your car has been driving for more than three years or 30,000 miles, then you probably need to replace it (especially if you can save money by doing it yourself).

A repair shop should be leery if it suggests you replace your air filter every time you get an oil change. Depending on conditions and mileage, drivers could typically go up to two years without changing an air filter in most cases.


What is the Recommended Period for Checking and Replacing my Air Filter?

Your car’s air filter should be checked once a year. The air filter is normally changed at this time, but according to some mechanics, it can last for up to 30,000 miles.

It may not be possible to reach those numbers in a year if you do a lot of traveling and driving. Nevertheless, you should check your air filter every year. If it appears to be dirty, replace it.

Avoid cleaning and reusing the filter. The best way to ensure your vehicle runs at its peak and stays in excellent condition is to replace its air filter.

How does the engine air filter work?

For combustion to occur properly, your engine needs a lot of air. You can keep your car’s intake system free of dirt, bugs, and debris by using a filter.

The engine warning light may come on if a clogged filter results in sluggish acceleration. Doesn’t that light drive you crazy?
