Replacing the aircon filter in your car is a relatively simple process that can be done at home with a few basic tools. This will save you money compared to taking it to a mechanic.

The aircon filter should be replaced every 12,000 to 18,000 miles or as needed, depending on your car's make and model. Regular replacement will help improve airflow and reduce the risk of mold growth.

A dirty aircon filter can decrease your car's fuel efficiency and increase your energy consumption. It's a good idea to check your owner's manual for specific instructions on how to replace the filter in your car.

Why Change the Aircon Filter?

Changing the aircon filter is essential to ensure clean air circulates through your car's cabin. A dirty filter can cause serious health problems, especially for people with respiratory issues.

Manufacturers recommend replacing the cabin air filter every 12,000 to 15,000 miles or at least once a year. However, there are some telltale signs that indicate it's time for a replacement.

Here are the 4 must-know signs that indicate an immediate replacement is needed:

  • Weak airflow from vents – If your AC or heater isn’t blowing as strongly, a clogged filter may be restricting airflow.
  • Bad odors inside the car – A dirty filter can trap mold, mildew, and bacteria, causing unpleasant smells.
  • Increased allergy symptoms – If you’re sneezing or experiencing itchy eyes while driving, the filter may no longer be effective at trapping allergens.
  • Noisy HVAC system – A clogged filter forces the system to work harder, causing unusual noises.

Why Is Change Essential?

A dirty aircon filter can lead to serious health problems, especially for the respiratory system, as it allows air contaminants to enter the vehicle's cabin.

As the aircon filter gets older, its pores get clogged with dust, debris, pollen, and micro particles from the air.

This can obstruct the airflow to the cabin, making the air feel stale and unpleasant.

If the aircon filter change is not done on time, air contaminants will pass through the old filter and enter the vehicle's cabin.

Not changing the aircon filter regularly can also lead to a decrease in the overall performance of the aircon system.
