Operating
After installing new filters and filling the water tanks, plug in your humidifier and power it on. Set your desired humidity level using the control panel. The humidifier will automatically operate to maintain the set humidity. The internal float mechanism will detect water levels and automatically shut off the unit when water is low, indicating it's time for a refill.

Maintenance
Regular maintenance is crucial for efficient humidifier performance and air quality:
- Filter Replacement: Replace filters regularly, typically every 30 to 90 days, or when you notice a decrease in humidification output or mineral buildup. Hard water conditions may require more frequent replacement.
- Cleaning: Clean the humidifier base and water tanks weekly with a mild disinfectant solution to prevent mineral accumulation and microbial growth.
- Hand Washing: Some wicking filters can be gently hand-washed and reused, though replacement is generally recommended for optimal performance. Refer to your humidifier's specific instructions for filter cleaning guidelines.
Troubleshooting
If you experience issues with your humidifier, consider the following:
- Decreased Humidification: This is often an indication that the wicking filters are saturated with mineral deposits and need to be replaced.
- Unpleasant Odor: A stale or musty odor can indicate microbial growth in the water tank or on the filters. Clean the unit thoroughly and replace filters.
- Humidifier Not Turning On: Check the water level. The float mechanism will prevent operation if water levels are too low. Ensure the unit is properly plugged in.
