Can PM 2.5 Enter a Car? Let’s Find Out! 💨💨
- Cars are equipped with air filters or cabin air filters capable of trapping particles as small as 0.3 microns (300 times thinner than a human hair). These filters help prevent small pollutants, such as road dust and exhaust fumes, from entering the cabin.
- However, PM 2.5 particles are so small that some can still seep into the car.
- When PM 2.5 levels exceed the standard limit, it may cause the air filter to become clogged. This can obstruct airflow into the cabin and allow more pollutants to pass through the clogged filter. It also makes the cooling system work harder.
Tips for Maintaining Your Car in Dusty Conditions:
- Use the car’s air recirculation mode to limit the intake of outside air.
- Replace the cabin air filter every 1 year or every 10,000-20,000 kilometers.
- Clean the car’s air conditioning system annually.
- Regularly clean the car, including washing and vacuuming the interior.
