How Often to Replace Air Filter in Car?

Determining when to Replace Air Filter in a car can be a bit tricky. Some may think it should be replaced every time they get an oil change, while others believe it can last for years without needing replacement.

So, what’s the deal? Should you change your car’s air filter more frequently during the summer months? Let’s delve into it.

We’re all aware that summer driving can take a toll on our vehicles. The intense heat can cause various parts to expand and tires to wear out faster. But does this mean air filters require extra attention during these hotter months? To answer that question, we first need to understand the role of an air filter.

How often should you change your Air Filters?

It’s recommended to change your air filters at least once a year or every 12,000-15,000 miles, whichever comes first. However, if you frequently drive in dusty or dirty conditions, you may need to replace your filter more frequently. Some filters come with a service life indicator that changes color when it’s time for replacement.

How to Change Your Car’s Air Filter

Ensuring that your vehicle’s airflow system operates efficiently is crucial for maintaining its performance. Changing the air filter is a fundamental aspect of this maintenance routine. Let’s walk through the process step by step.

1. Select the right filter: Begin by choosing the appropriate air filter for your car. Filters vary depending on the make and model of your vehicle. Purchase the correct one before proceeding.
2. Locate the filter housing: Open the hood of your car and locate the air filter housing. It is typically found near the engine and is enclosed within a plastic or metal casing.
3. Remove the old filter: Depending on the design of the housing, you may need to unscrew or unsnap any clips holding it in place. Be careful not to damage any surrounding parts as you remove the old filter.
4. Insert the new filter: Take out the old filter and replace it with the new one. Ensure that the new filter fits snugly within the housing, covering the entire opening.
5. Reattach clips or screws: Once the new filter is in place, reattach any clips or screws that secure the housing. Ensure that everything is tightly fastened to prevent any air leaks.
6. Double-check for security: Before closing the hood, double-check that the filter is securely installed and that all fasteners are properly tightened.
7. Clean up: Clean up any debris or dirt around the filter housing area before closing the hood.
8. Close the hood: Lower the hood of your car securely, ensuring that it latches properly.

The benefits of changing your air filters more often:

1. Reduced emission of pollutants: A clogged air filter can hinder the cleaning of air entering the engine intake valve and cabin compartment. This can cause your car’s system to work harder to circulate clean air, leading to increased emissions.
2. Improved air quality: A dirty cabin air filter can result in the AC venting poor-quality air into the cockpit. Changing the air filter more frequently can help enhance the air quality inside your car, creating a better environment for you and your passengers.
3. Reduced allergy symptoms: Changing the cabin air filter more frequently can be especially beneficial if you or your family members suffer from allergies. This helps to decrease allergens in the air, contributing to a more comfortable environment for everyone.
4. Improved gas mileage: Changing your car’s air filter more often can also lead to improved gas mileage. When airflow to the engine is restricted due to a dirty filter, your vehicle consumes more fuel. By replacing the air filter regularly, you can help enhance gas mileage and save money at the pump.
