A DIY Guide to Upgrading Your Car's Interior Air Quality

The air inside your car's cabin can be up to six times more polluted than the air outside, according to the Environmental Protection Agency (EPA). This can cause health issues like headaches, allergies, and respiratory problems.

Changing your car's cabin air filter regularly can improve the air quality inside your car and reduce the risk of health problems. A new filter can trap pollutants and keep the airflow into your car's cabin clean and fresh. Changing your cabin air filter every 12,000 to 15,000 miles or once a year is recommended.

Signs Of A Dirty Cabin Air Filter

A dirty cabin air filter can manifest in several ways that affect your driving experience. One telltale sign is a musty or moldy odor from your car's vents. This can be caused by the accumulation of dust, dirt, and other particles in the filter, which then become a breeding ground for bacteria and mold.

Another sign of a dirty cabin air filter is reduced airflow through the vents. As the filter becomes clogged, it restricts the amount of air that can pass through, which can cause your car's heating and cooling system to work less efficiently. This can result in longer wait times for your car to reach your desired temperature.

Lastly, a dirty cabin air filter can increase allergens and pollutants in your car's cabin. If you or your passengers experience more sneezing, coughing, or other allergy symptoms while driving, it may be time to replace your cabin air filter.

Benefits Of Changing Your Car's Cabin Air Filter

Changing your car's cabin air filter is an essential maintenance task that can provide numerous benefits:

  1. A clean filter ensures that the air quality inside the car is healthy and free from pollutants, such as dust, pollen, and mold spores, which can cause respiratory problems.

  2. It helps prolong the lifespan of the car's heating and air conditioning systems by reducing the strain caused by a clogged filter. This can save you money on expensive repairs in the long run.

  3. A clean cabin air filter can also improve the overall driving experience by reducing noise and odors inside the car, providing a more comfortable and pleasant ride.

How to Change Your Car's Cabin Air Filter

Identify The Type Of Cabin Air Filter For Your Car

The first step to changing your car's cabin air filter is to locate the filter. The cabin air filter is typically located behind the glove compartment or under the car's passenger-side dashboard. Once you have located the filter, determine the type of filter that your car uses.

There are two types of cabin air filters particle filters and activated carbon filters. Particle filters capture dust and other small particles, while activated carbon filters are designed to remove odors and pollutants from the air.

Gather The Necessary Tools And Supplies

The first step to changing your car's cabin air filter is to identify your car's required filter. Some vehicles may have multiple cabin air filters, such as activated carbon or HEPA. To determine the type of filter, consult your vehicle's owner's manual or research online. Once you know the type of filter, locate the filter's housing within your vehicle. The filter housing is usually located behind the glove box or under the dashboard.

Remove The Old Cabin Air Filter

Before changing the cabin air filter, you must gather the necessary tools and supplies. The tools you'll need typically include a screwdriver, pliers, or a socket wrench, depending on the type of filter housing. You'll also need a new cabin air filter that matches your vehicle's specifications. Additionally, you may want to wear gloves and a face mask to protect yourself from any dust or debris that may be present.

Once you have all the necessary tools and supplies, you can change your car's cabin air filter. Follow your vehicle's owner's manual instructions, or consult a professional mechanic for additional guidance. Remember to replace your cabin air filter regularly to ensure that your vehicle's air conditioning system works efficiently and to maintain good air quality inside your car.

Install The New Cabin Air Filter

Inserting the new cabin air filter, check the direction of the airflow arrows on the filter. This will ensure that the filter is installed correctly and will function effectively. Insert the new cabin air filter into the slot, ensuring it is securely in place. Next, replace the filter cover and secure it with any clips, screws, or tabs removed.

Dispose Of The Old Cabin Air Filter

Now that you have successfully installed your new cabin air filter, it is essential to dispose of the old filter properly. First, check your local regulations for the proper disposal of the old filter, as some areas may require special disposal methods.

You can generally dispose of the old filter in the trash, as it is not considered hazardous waste. However, sealing the old filter in a plastic bag is essential to prevent any dirt or debris from escaping. With these steps, you can easily change your car's cabin air filter and ensure you are breathing clean air while driving.

Test The New Cabin Air Filter

Installing a new cabin air filter and testing it to ensure it's working properly is essential. To do this, turn on your car's air conditioning system and check for proper airflow. Then, place your hand in front of the vents and feel the air flowing smoothly and strongly. If the airflow is weak or not coming out, there may be a problem with the air conditioning system that needs to be addressed before proceeding with the cabin air filter change.

Once you've confirmed that the air conditioning system is working properly, you can replace the cabin air filter. This simple maintenance task can help improve the air quality inside your car, reduce allergens and dust, and improve the performance of your air conditioning system.
