The Best Car Air Filters of 2020

Bring clean air into your vehicle.

One of the most important, but often overlooked parts of a car is the cabin air filter. This filter purifies the air that circulates inside your car. Most modern cars already have air filters installed, but some are of an undesirably low quality.

The best car air filters will capture dust, pollen and other pollutants while removing odors. Some effective filters will even remove harmful gases and exhaust fumes. Therefore, choosing the right one is crucial.


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).

So what is found in car exhaust? Here are a few potentially harmful pollutants:

  • Ozone: This is a colorless, odorless gas that’s harmful when at ground level. Sunlight reacts with the nitrogen oxide a car emits, and VOCs found in the air, and creates 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 damage to the lungs (4).
  • Carbon monoxide: Is an odorless, colorless gas that’s highly poisonous. It can cause dizziness, confusion and fatigue when inhaled (5).

If that isn’t enough, there’s also dust, pollen and other allergens that could 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. Due to the enclosed space of a car cabin, odors seem to build up quicker and linger for longer.

Installing a good-quality air filter is an excellent way to keep most pollutants at bay. Now, we say “most” because what the filter will remove depends on the quality. Some filters will effectively capture and remove odors, allergens and fumes. Others, on the other hand, will only take care of larger particles such as dust, leaves and pollen.

Another effective tool is an air purifier. These are normally used within our homes to improve indoor air quality. However, air purifiers are becoming more and more popular for car use as well.

Finding the Best Car Air Filters

There’s a wide choice available on the market when it comes to 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 with bad odors within your car, a filter with carbon and baking soda 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 to capture finer particles of dust and pollen as well as 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. For people living in remote areas, though, a dust filter should be sufficient.


The Best Car Air Filters of 2020

In our quest to find the best car air filters, we took affordability and value for money into consideration.

After looking through car air filters recommended by experts, we found our top seven.

1. ACDelco CF188 Cabin Air Filter

Best Car Filter Overall

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.

The three layers work effectively together to capture both large and small particles. Larger pollutant particles will be caught in the first layer, while the middle layer captures small particles. Fumes and unpleasant odors will also be removed to give you and your passengers a pleasant ride.

Because of the different layers, the filter separates the pollutants and contains them much better, so nothing escapes. This filter was made to fit General Motors (GM) vehicles, so before buying, make sure it will fit your car.

You get great value for money since the filter is durable and works very efficiently. Most customers were pleased with how easy it was to install, even for those who claimed not to be as knowledgeable.

PROS:
  • Keeps pollutants separated.
  • Consists of three layers.
  • Removes fumes and odors.
  • Easy to install.
CONS:
  • Only compatible with GM vehicles.

2. EPAuto Premium Cabin Air Filter CP285

Best Premium Filter

EPAuto CP285 (CF10285) Replacement for Toyota/Lexus/Scion/Subaru Premium Cabin Air Filter includes Activated Carbon
Check Price

The CP285 is an excellent filter if you want fresh air within your car. It uses a carbon and baking soda filter to enhance the air quality and remove unpleasant odors and fumes.

Both carbon and baking soda are highly effective at absorbing odors. It’s often recommended to place an open box of baking soda inside your car to absorb bad odors. Here, it’s inside the air system of your car, removing any odor before it makes its way into the cabin.

One of the best things about this filter is that it fits a variety of cars and models. It’s easy to install and lasts a long time. Replacing the filter is also inexpensive as it’s highly affordable and offers great value for money.

EPAuto recommends that the filter is changed every 12 months or 12,000 miles. Depending on how much it’s used, replacing it once a year is easily done without taking a huge chunk out of your wallet.

There has been a bit of confusion going around due to the “up” arrows on the filter. Many users confused this with an indication of airflow. However, when installing, the arrows should be pointing up.

PROS:
  • Contains baking soda.
  • Removes bad odors.
  • Lasts a long time.
  • Affordable in the long run.
CONS:
  • It doesn’t come with any instructions.

Improving Your Car

Car air filters are often overlooked, which is a shame. These are easily installed and replaced when needed, and help to keep dust, odors and allergens out of the cabin.

When searching for the best car air filters, consider what your biggest issues are. Is it odors? Dust or allergens? Another thing to consider is where you live since big cities are more polluted than remote areas.
