You should generally change your car's AC filter every 10,000 kilometers in polluted areas and every 20,000 kilometers in normal areas.
Here's a more detailed explanation:
-
General Recommendations: As a rule of thumb, aim to replace your cabin air filter (AC filter) annually or as recommended by your vehicle's manufacturer in the owner's manual.
-
Environmental Factors: The frequency of replacement largely depends on your driving environment.
- Polluted Areas: If you frequently drive in areas with heavy pollution, dust, or pollen, you should replace the filter more often, approximately every 10,000 kilometers.
- Normal Areas: If you primarily drive in cleaner environments, you can extend the replacement interval to around 20,000 kilometers.
-
Signs You Need to Replace Your AC Filter:
- Reduced Airflow: If you notice a decrease in the airflow from your AC vents.
- Unpleasant Odors: If you smell musty or unpleasant odors when the AC is running.
- Increased Allergies: If you experience increased allergy symptoms while driving.
- Noisy AC: Unusual noises coming from your AC system can sometimes indicate a clogged filter.

Why Replace Your AC Filter?
- Improved Air Quality: A clean filter ensures that the air circulating in your car is free from dust, pollen, and other pollutants, improving the air quality for you and your passengers.
- Efficient AC Performance: A clogged filter restricts airflow, forcing your AC system to work harder and reducing its efficiency. Replacing the filter helps maintain optimal performance.
- Extends AC System Life: By allowing proper airflow, a clean filter helps prevent strain on the AC system, potentially prolonging its lifespan.
-
DIY Replacement: Changing your car's AC filter is usually a simple process that you can do yourself, saving you money on labor costs. Consult your owner's manual or search online for specific instructions for your vehicle model.
By regularly replacing your car's AC filter, you can ensure clean air, efficient AC performance, and a healthier driving environment.
