How to clean the transducer
Weekly cleaning procedure
Remove the water tank from the humidifier base. Remove the air diverter from the reservoir. Empty any water from the reservoir. Apply a vinegar soultion (50/50 mix of white vinegar and water) or detergent (small amount) to the surface of the transducer and allow it to soak for 2-5 minutes. After 2-5 minutes, wash out the solution. Wipe away any debris with a clean soft cloth or brush. Place the water tank back onto the humidifier base.
