Operating Principles
The wick filter functions by absorbing water from the humidifier's reservoir. As air passes through the moistened wick, water evaporates, adding humidity to the air. The filter's material is designed to capture waterborne minerals and contaminants, ensuring that only clean, pure moisture is released into your room. The integrated antimicrobial coating helps maintain hygiene by inhibiting the growth of bacteria within the filter.
Maintenance
Regular maintenance of your wick filter is crucial for optimal humidifier performance and air quality.
- Replacement Schedule: It is recommended to replace the wick filter every 6 months, based on approximately 10 hours of daily use. Actual replacement frequency may vary depending on local water quality and usage habits.
- Antimicrobial Protection: The filter includes a built-in antimicrobial coating to help inhibit bacterial growth and extend the filter's effective life.
- Washable Design: The filter features a machine washable design, which can extend its lifetime up to 1 year. Refer to your humidifier's main manual for specific washing instructions.

Troubleshooting
If you experience reduced humidification or notice unusual odors, your wick filter may need attention.
- Reduced Humidification: If your humidifier is producing less moisture than usual, the wick filter may be saturated with minerals or nearing the end of its lifespan. Inspect the filter for discoloration or hardening.
- Unusual Odors: A persistent musty or unpleasant odor from the humidifier can indicate bacterial growth on the filter. Ensure regular cleaning and timely replacement.
- Filter Change Alert: Your Blueair humidifier is equipped with an alert system to indicate when it's time to change the filter. Pay attention to these indicators.
