Ultrasonic Essential Oil Diffuser 400ml USB Colour-Changing Oslo

A soft veil of scented mist, a ring of gentle colour, and no flame to watch over. This ultrasonic essential oil diffuser turns water and your chosen oil into a cool fragrant mist, giving a desk, bedside table or quiet corner a more considered atmosphere in moments. Its wood-effect plastic body keeps the look warm and natural, while the electric format feels clean and modern.

The room-changing ritual

• The mist brings scent into the room without a candle, incense stick or open flame.
• A colour-changing LED light adds a low, ambient glow beneath the carved-look top.
• The rounded form sits softly in a space, with a pale band of light around the middle.
• The wood-grain finish gives the diffuser a calmer, more organic presence than plain plastic.
• Use it while working, reading, stretching or settling the room for the evening.

Ultrasonic mist, made simple

The diffuser uses ultrasonic waves to break water and essential oil into a fine, cool mist. It does not rely on heat, so the ritual feels clean and controlled: fill the tank, add your chosen oil, switch it on, and let the scent move gently through the space.

What to use with it

Add water to the tank and a small amount of essential oil suitable for diffusers. Change the oil depending on the moment: something bright for the morning, something resinous for a slower evening, or a familiar favourite when you want the room to feel like your own.

Wood-effect finish and soft light

The body is plastic with a warm wood-effect pattern, shown with a rounded, low profile and decorative cut-outs on the top. Small control buttons sit on the front, with indicator lights above them, keeping the practical parts neat and easy to read.

How to use and care for it

Place it on a stable, level surface before filling. Use clean water, add essential oil, then set the mist and timer functions as preferred. The diffuser has an automatic power-off function when the water runs out.

Empty the tank between uses if water is left inside, and wipe the interior with a soft cloth. Keep the USB connection dry and avoid placing the diffuser where it could be knocked over.

A modern scent ritual

Electric diffusers sit somewhere between fragrance, light and daily routine. Unlike incense or candles, they create atmosphere without smoke or flame, which suits shared spaces, work desks and homes where scent is part of the background rather than the centre of attention. The ultrasonic style is valued for its simple water-and-oil ritual: a few quiet steps before the mist appears, turning fragrance into something visible as well as scented.
