Where essential oils can go

HumidifierVerdict: YES, WITH LIMITSYes, with limits. Put essential oil in the water tank only when the manual for that exact humidifier says the tank is oil-compatible. If the unit has an aroma tray, pad, or cup, use that part and keep oil out of the tank; if the manual is silent, use a separate diffuser. Oil in an unapproved tank can damage the humidifier and may void its warranty.
