Operating Instructions
Once the BestAir ALL-2 filter is installed, operate your humidifier according to its manufacturer's instructions. The filter works by absorbing water from the reservoir and allowing the humidifier's fan to blow air through the moistened wick, releasing invisible moisture into the air. The anti-microbial treatment helps ensure cleaner humidification.
For optimal performance, ensure the humidifier's water tank is regularly filled and the unit is placed in an appropriate location as recommended by your humidifier's manual.
Maintenance
Regular maintenance of your BestAir ALL-2 filter is crucial for efficient and hygienic humidifier operation.
- Filter Replacement: Replace your humidifier filter regularly, typically every 1-3 months, or more frequently in areas with hard water or heavy usage. A discolored, hardened, or calcified filter indicates it needs replacement.
- Cleaning: Do not attempt to wash or clean the filter. Washing can damage the filter material and reduce its effectiveness, including the anti-microbial treatment. Replace with a new BestAir ALL-2 filter when necessary.
- Humidifier Cleaning: Periodically clean your humidifier's water tank and base according to its manufacturer's instructions to prevent mineral buildup and bacterial growth.
