Can I add scents, medications, oils, etc. to my water tank?
PureGuardian® Ultrasonic Humidifiers can NOT have scents, medications, etc. added to the tank. These substances will clog up and prevent the humidifier from functioning properly.
*Although, we do sell humidifiers with aromatherapy trays. Aromatherapy tray option helps create a relaxing environment with essential oils. The humidifiers that include aromatherapy trays are: H940AR, H965AR, H1210AR, H1250AR, H4750AR, and H4810AR.
