Filter Care and Maintenance
Regular cleaning of your filter is crucial for maintaining optimal performance and extending its lifespan. Follow these guidelines:

- Rinse Before Initial Use: Always rinse the new filter under running water before its first use.
- Hand Wash Only: Never machine wash the filter. Hand washing helps preserve the filter's structure and effectiveness.
- Rinse with Water or Soft Brush: Use clean water to rinse the filter. For stubborn buildup, gently use a soft brush.
- No Detergents or Cleaners: Avoid using any detergents, soaps, or chemical cleaners, as these can damage the nano material and impair performance.
- Clean Weekly (or Every 3 Days with Hard Water): For regular use, clean the filter weekly. If you live in an area with hard water, clean the filter every 3 days to prevent mineral buildup.
- Do Not Wring; Reinstall Wet: After cleaning, do not wring or twist the filter, as this can damage its delicate fiber structure. Reinstall the filter while it is still wet.
Filter Lifespan: Each filter is designed to last 6-12 months, depending on usage and water quality. Replace the filter when you notice a decrease in humidification efficiency or if it appears heavily soiled despite cleaning.
Troubleshooting
- Reduced Humidification: If your humidifier's output decreases, first ensure the water tank is full. If the issue persists, clean the filter as per the maintenance instructions. If the filter is old (beyond 6-12 months), it may need replacement.
- Unpleasant Odor: An odor may indicate bacterial growth. Clean the filter and water tank thoroughly. If the odor persists, replace the filter.
- Humidifier Not Turning On: Ensure the filter is correctly installed and the humidifier's main unit is properly assembled and plugged in.
