The ACDelco cabin air filter consists of a three-layer media that promises to filter out pollutants such as dust and pollen. It’s a non-woven filter that captures more particles while increasing airflow within the car’s AC.

Why You Need a Car Air Filter
The closed space of a car is often more polluted than the outside. This is due to the impurities the HVAC system brings inside. Studies show most of the pollutants found inside a car are from the vehicles in front of you (1).
The harmful pollutants include:
- Ozone: This is a colorless, odorless gas that’s harmful at ground level. The sunlight reacts with the nitrogen oxide a car emits, and VOCs found in the air and create ozone (2).
- Nitrogen dioxide: A pungent-smelling gas that can cause respiratory issues such as lung irritation and breathing problems (3).
- Sulfur dioxide: This gas can cause respiratory issues such as shortness of breath. It can also cause chest pain and permanent lung damage (4).
- Carbon monoxide: Is an odorless, colorless gas that’s highly poisonous. When inhaled, it can cause dizziness, confusion, and fatigue (5).
If that isn’t enough, dust, pollen, and other allergens could also find their way into your vehicle.
Bad odors are another common complaint within a car. These could be caused by leftover food debris, pet messes, children’s messes, or even mold.
Installing a good-quality air filter is an excellent way to keep most pollutants at bay.
Finding the Best Car Air Filters
There’s a wide choice available on the market regarding air filters for your car. It can get overwhelming, but knowing what to look for can make it easier.
Odor Removal
If you’re struggling to remove bad odors from your car, a carbon and baking soda filter is efficient. These filters have baking soda and activated carbon woven into the pleats. As air passes through the filter, the baking soda absorbs odors while carbon absorbs fumes and gases.
Dust and Allergen Removal
A thick filter will help capture finer particles of dust and pollen and some allergens. Where you live also plays a significant role in what filter you need. People living in polluted cities will need a more thorough filter. A dust filter should be sufficient for people living in remote areas.
Durability and Mileage
How long a car air filter lasts is based on mileage. For example, you should replace your air filter after a certain number of miles. On average, this is between 12,000 and 15,000 miles which is decent durability. Any less than 10,000 miles, the air filter might not be as durable.
FAQs
How Often Should You Change Air Filter In Car?
The frequency you change an air filter in a car depends on which filter you are changing. A cabin filter should be changed every 12,000 to 30,000 miles, while you should change the engine filter every 30,000 miles.
However, the engine filter does vary between manufacturers. Ford recommends a change every 30,000 miles, while Chevrolet stipulates every 45,000 miles. Hyundai state you should swap the engine filter every 15,000 miles.
What are the Signs of a Dirty Engine Air Filter?
The signs of a dirty engine filter include a slower acceleration time, issues starting the car, and thick black smoke billowing from the exhaust. Your engine needs the correct air-to-fuel ratio, so when the filter is blocked, it upsets the balance, causing the fumes to run black.
Does a New Air Filter Improve Car Performance?
A new air filter will improve car performance because it ensures a healthy airflow, which means the car has the correct air-to-fuel burning ratios.
Is a Dry or Oiled Air Filter Better?
To know whether a dry or oiled filter is best depends on a couple of variables: airflow and filter performance. Most engines use a dry filter, which is better for filtration but not for airflow. Oil filters are less restrictive and give better airflow.
Can I Wash the Air Filter of My Car?
You can clean your car’s air filter with soapy water, provided you give it ample time to dry. It enhances the vehicle’s performance and saves you the cost of a new one.
