Essential oils can be corrosive so it’s important that the customer understands the importance of not letting the oils touch surfaces or the diffuser. They should wash their hands before they touch the unit, furniture, or adapter.
All of our units’ water tanks are made of oil-resistant PP (polymer polypropylene) plastic and are BPA free.
All NOW diffusers are in RoHS (Restriction of Hazardous Substances) compliance.
