What Are Car Air Filters For?

In most cars, there are two air filters: one for the engine and one for the cabin. Both are vital to the proper operation of your vehicle, and keeping a constant check on their condition is essential.

The screens are composed of materials that are permeable, such as paper, cotton, or foam. Sand, pollutants, dust, pollen, and even mould are trapped by them before they reach you or the engine.

Filters for Engines

The quality of the air entering the engine has a significant impact on its performance. These particles would make their way in without screens, causing damage to the engine’s cylinder walls and pistons.

Filters for Cabins

Air pollution kills millions of people every year, whether it’s inside your house or while driving a car. It leads to cardiovascular and respiratory problems over time.

Cabin air filters with high effectiveness, such as HEPA filters, are beneficial in this situation. They can catch 90% or more of all particles 0.3 microns or bigger, saving drivers’ health considerably.

How Often to Change Engine Air Filter

Although there is no one-size-fits-all timetable, there are certain principles to follow.

Frequency of Driving

The frequency with which you should change your car’s air filter is determined by how frequently you drive. It should be changed every 30,000 miles in general.

Over time, the fragile material may break, allowing debris to enter. However, regardless of usage, the screen should be replaced every three years.

Model of Your Vehicle

When it comes to filter maintenance, each manufacturer may have a different suggestion. They’re generally located in the owner’s manual for your car. Chevrolet, for example, advises filter replacement every 45,000 miles. Ford, on the other hand, recommends replacing it after 30,000 kilometres (5).

Conditions for Driving

Filter changes will become more frequent as a result of certain conditions. When driving on rough roads, in hot weather, or in heavy traffic, Hyundai recommends replacing it every 15,000 miles. This also includes driving in a heavily polluted area.

Look for the following hints:

Here are some more useful hints if you haven’t kept track of your driving mileage.

  • Low Power:
    • A blocked filter might create ignition problems, making it difficult to start your car. However, contrary to popular belief, a filthy filter does not always imply that you will use more gas.
    • However, it does reduce acceleration power by 6 to 8%. If your automobile is slow to accelerate, this might be an indication that your screen needs to be replaced.
    • However, keep in mind that it usually develops gradually, so you might not notice it immediately away.
  • Visual Inspection
    • A simple glance at the filter might indicate when it’s time to replace it. If the screen is any colour other than white or grey, it’s apparent that it has to be replaced.
    • Depending on the vehicle’s manufacture, most automobile owners replace the engine oil every 3,000 to 15,000 miles (8). It’s typically a good idea to check all filters at the same time, whether professionally or on your own.
  • Black Smoke
    • To run smoothly, an engine requires around 2,641 gallons of air to fuel one 0.3 gallon of gas. The gasoline will then leave a dark deposit in your exhaust, causing it to emit thick, black smoke.
    • This indicates that your engine is getting enough air and oxygen, and the air filter should be replaced.

How Often to Change Cabin Air Filter

Cabin air filters should be updated once a year or every 12,000 to 30,000 miles, whichever comes first. This filter is likewise dependent on the purposes and circumstances we discussed earlier. Here are several signs that your cabin filter needs to be replaced:

There are foul odours throughout the cabin.
Airflow via the cooling or ventilation system is reduced.
There is a lot of noise from the air circulation.
When you’re driving, you’re suffering from allergies or other respiratory problems.

How to Change an Air Filter

The filters may be replaced at a car dealership. Regardless, both the engine and cabin filters are simple to inspect and replace if necessary.

Engine Air Filter

This filter is usually located within a filter box beneath the hood. Some may be accessible by just opening the box, while others will require the use of a screwdriver. When buying a new screen, make sure it fits the dimensions of the package.

Cabin Air Filter

The cabin air filter is usually found beneath the glove box or under the dashboard in most automobiles. It may take a little longer the first time, but it is a simple process that most people can handle.

Bottom Line How Often to Change Air Filter in a Car

To maintain your car and lungs in good working order, both the engine and cabin air filters are required. The frequency with which you should change your car’s air filter is determined on the distance travelled. However, several visual clues might help you determine whether the screen needs to be replaced.

It’s worth noting that not all filters need to be replaced; some types are washable, making them more environmentally friendly. If you choose a one-time-use filter, don’t toss it away; many retailers will recycle it. Make sure the screen you choose will fit in its designated location.
