Why Aetheo
The Aetheo 120ml USB Aromatherapy Diffuser is part of the Aetheo home fragrance range, designed for everyday essential oil diffusion in compact spaces. Compatible with any 100% pure essential oil, including the Aetheo essential oil range.
What power source does it use?
The diffuser is USB powered and connects to any standard USB port — a laptop, desktop, USB hub, or USB wall adaptor (not included). It does not require a direct mains connection. The USB cable is included.
What essential oils can I use?
Use 100% pure essential oils diluted in water — add 3–5 drops per full tank. Do not add oil without water. Do not use synthetic fragrance oils or perfume blends. Some oils (such as Cinnamon Bark and Clove Bud) are high-irritant; use in well-ventilated spaces and at lower drop counts. Check individual oil safety data before use.
Is the colour-changing light adjustable?
The diffuser features a colour-changing ambient night light. Refer to the included instructions for the available light modes — including how to select a fixed colour, cycle through colours, or switch the light off independently of the mist function.
How long does a full tank last?
Runtime depends on the mist setting selected. The 120ml tank is designed for shorter sessions. Refer to the included instructions for available mist output settings and estimated runtime per setting. Refill the tank as needed — do not run the diffuser with an empty tank as this may damage the ultrasonic element.
Is it suitable for use around pets or children?
Some essential oils are unsuitable for use around cats, dogs, and other pets — particularly those containing phenols (such as Cinnamon Bark or Clove Bud) and certain terpenes. Diffuse in a well-ventilated space with an exit route available for pets. Consult a veterinary practitioner for specific guidance. Keep the diffuser and any essential oils out of reach of children.
