A clean filter ensures proper airflow for efficient purging and prevents contaminants from entering the canister, which could degrade its performance.

The vapor canister filter is generally designed for long-term use. However, its lifespan can be affected by environmental factors such as dust, dirt, and humidity. While there isn't a strict replacement interval for this specific filter, it is advisable to inspect it periodically, especially if you drive in dusty conditions or experience EVAP system-related issues.
Tirotiro:
- Visually inspect the filter for any signs of physical damage, cracks, or blockages.
- Check the hose connections for secure fitment and absence of leaks.
- If the filter appears excessively dirty or clogged, replacement may be necessary.

- Kakara Wahie: While less common for a filter, a strong fuel odor could indicate a leak in the EVAP system, which should be investigated thoroughly.
Note: These symptoms can be caused by various components within the EVAP system. A professional diagnostic scan is recommended to accurately identify the root cause.
