Normal replacement interval
What counts as normal driving
Baseline intervals apply to standard city/suburban driving with moderate pollen exposure and typical road dust.
- Baseline replacement interval: about 30,000 miles (48,000 km) or 2 years under normal driving conditions.
- In dusty, polluted, or high-pollen environments (or if you drive with pets or have allergies), consider replacing around 15,000–20,000 miles (24,000–32,000 km) or roughly once per year.
These figures provide a practical starting point. Your own vehicle may be different depending on year and local conditions.
