Ultrasonic Aromatherapy Essential Oil Diffuser & Humidifier

Ultrasonic Aromatherapy Diffuser & Starter Oil Set Everything you need to start sleeping better tonight.

The hour before bed matters more than most people realise. What your senses experience in that window — the light, the sound, the scent — directly signals your nervous system whether it's time to stay alert or wind down. This diffuser helps you get that signal right, every night.

It works ultrasonically, meaning it uses vibration rather than heat to break your essential oils into a fine mist. That matters because heat destroys the active compounds in essential oils — the very things that make them effective. Cold mist diffusion keeps them intact and delivers them exactly as nature intended.

Fill it up before bed, add a few drops of your chosen oil, and let it do the rest. The 300ml tank runs for up to 8 hours — enough to last through the night without a refill.

Six oils included — so you can find what works for you

Everyone responds differently to scent. That's why this set comes with six starter essential oils covering the full range of sleep and relaxation needs:

• Lavender — the classic sleep oil. Calms the nervous system and slows your heart rate
• Eucalyptus — clears the airways for easier, deeper breathing through the night
• Orange — warm and uplifting. Takes the edge off stress and anxiety before bed
• Tea Tree — purifies the air and creates a clean, fresh sleep environment
• Lemon — light and clarifying. Helps clear a busy, cluttered mind before sleep
• Mint — cool and refreshing. Eases tension headaches and helps you physically unwind

Try them individually, blend two together, or follow our guides in the Learn section to find the right combination for your sleep type.

It doubles as a mood light

The soft colour-changing LED creates the kind of gentle ambient light that actually supports sleep — warm and dim, nothing like the harsh blue light of a screen. Cycle through colours, settle on your favourite, or switch the light off entirely. Your call.

Simple to use. Easy to clean.

No complicated settings, no app required. Fill, add oil, switch on. The wide-mouth tank means cleaning takes seconds rather than minutes — which matters when you want this to be a daily habit, not a chore.
