Latest Allergies News
- Set the device to between 30 percent and 45 percent humidity.
- Regularly clean the humidifier according to manufacturer's instructions to prevent mold growth.
- Change the filter frequently.
- Use demineralized or distilled water instead of tap water. This may help reduce bacterial growth and production of a white dusty film.
