Replacement Air Sensor for AromaLink Diffuser

The Air Sensor is an optional accessory designed for use with the AromaLink diffuser, allowing it to detect airflow and operate only when your HVAC system is running. When installed, the sensor monitors air movement across the diffuser, enabling you to program it to activate only when your HVAC fan is on. This ensures efficient fragrance distribution while conserving fragrance when the system is not in use. Ideal for users integrating their diffuser with central air systems, the Air Sensor provides a seamless, automated scenting experience. **Every AromaLink diffuser includes an Air Sensor at the time of purchase.**
