The Levoit Vital 100S Smart (model LAP-V102S-WUS) uses a multi-stage filtration system that includes a washable pre-filter, an activated carbon filter, and a True HEPA filter. Replacing the filter on time ensures the purifier continues delivering clean air and optimal performance.
When to Replace the Filter
- The Check Filter Indicator will light up when the filter needs replacement.
- Depending on usage and air quality, filters typically last about 6–12 months.
- If airflow decreases noticeably or odors persist, it may be time to replace earlier.
Preparation
- Turn off and unplug the air purifier before replacing the filter.
- Have a genuine Levoit Vital 100S Smart replacement filter ready.
- Prepare a clean, flat surface to place the unit while working.
Steps to Replace the Filter
- Power off and unplug the unit.
- Open the back cover by pressing the release tabs.
- Remove the old filter carefully and dispose of it properly.
- Clean inside the filter compartment with a dry, soft cloth if dust has accumulated.
- Insert the new filter into the compartment, ensuring the pull tabs face outward for easy removal next time.
- Close the back cover securely until it clicks into place.
Resetting the Check Filter Indicator
- After replacing the filter, press and hold the Check Filter Button for 3 seconds until the light turns off.
- This resets the indicator so the purifier can track the new filter’s lifespan accurately.
Maintenance Tips
- Wash the pre-filter every 2–4 weeks to extend the life of the main filter.
- Keep the purifier away from moisture and direct sunlight.
- For best results, use the purifier continuously in Auto Mode so the fan adjusts automatically based on air quality.
