The cabin air filters in cars often go overlooked as the tell-tale signs of them needing to be switched can be easily overlooked. A general rule of thumb is that these filters need to be replaced every 15,000 to 30,000 miles, but this can vary. For this reason, it is vital to know the signs of an old cabin air filter.

Four signs that your Cabin Air Filters need to be Replaced:

  1. The air coming out of the filters has a smell: This smell will be a musty scent that signifies the worn-out nature of the cabin air filters. If this smell lingers for multiple days, it may be time to switch your cabin air filters.
  2. The airflow is reduced within the cabin: The old dirty air filter can prohibit the airflow as the cabin air must go through the system and the filter. If you find that the airflow within your car's cabin is reduced, even with the air conditioning on full blast, this may be a sign that it is time to replace the filter.
  3. You notice an increasing amount of dust on the dashboard of your vehicle: Because the air flows through the filter, an old filter can cause a build-up of dust within the car. If you find that there is significantly more dust in the car over a couple of weeks, specifically on the dashboard, this is a sign you are due for an air filter change.
  4. Your air conditioner sounds louder than usual: If it sounds as though your air conditioner is blowing louder and more challenging than previously before, don't worry, it may just be time to switch the cabin air filter. This more audible sound is produced when the air conditioning in your cabin has to work harder to create sufficient airflow.

Find the correct Air Filter:Finding the right air filter for your replacement is essential. Cabin air filters generally range from 15$ to 50$ for original premium equipment.
Safety: Before beginning the replacement process, it is important to park your vehicle in a safe and flat area. It is also essential to make sure that your vehicle's parking brake is on before you begin to ensure that the car is stationary throughout the process. Additional steps that can be taken for safety may include safety goggles and gloves, as many air filters may be filthy depending on the last time they were replaced. You may also want to cover the passenger seat floor to avoid any dirt or debris that may fall during the replacement process.
Accessing the Air Filter: Opening and sometimes removing the glove box to gain access to the air filter is the first step. The owner's manual of your vehicle will be able to provide vehicle-specific information on how to remove the glove box or access the air filter. Sometimes this step requires a screwdriver, while it is as simple as pressing on a tab for other vehicles. It is essential to consult your driver's manual or repair guide to make sure you can adequately access the cabin air filter for your car.
Remove the Old Filter: Once properly accessed, it should be easy to remove the old filter. When removing the filter, make sure to clear any additional dust and debris from the space. It may be necessary to vacuum the space so that the new filter has a clean area to be placed. When removing the old filter, it is also essential to pay attention to the direction it was installed to replicate the installation with the new filter.
Install the New Air Cabin Filter: When putting in the new filter, it is vital to pay attention to the direction of the new filter. There are also usually arrows to signal airflow direction to make installation that much easier.
Put the Glove Box Back: Follow the steps you used to remove the glove box, and you're all set!
