Hotel-style fragrance without the water or the mess

For anyone who loves walking into a beautifully scented home, this waterless diffuser spreads pure fragrance oil through cold air with no water, no steam and no damp patches. It is mains powered: fill the container with oil, plug it in and choose an intensity setting; the diffuser then cycles between short bursts of 10 to 25 seconds and longer rests of 60 to 220 seconds, so a bottle goes a long way. It runs almost silently in living rooms, bedrooms and offices, and a customisable, energy-efficient LED night light adds a calming glow in the evening. Refillable oil bottles let you switch scents to match the season.

Why you'll love it

Truly waterless: diffuses neat fragrance oil, so no refilling tanks or mess
Mains powered: fill, plug in and enjoy, no batteries to replace
Whisper-quiet: near-silent operation for bedrooms and offices
Night light: customisable, energy-efficient LED glow
Cycled diffusion: on/off intervals adjust with the intensity you select

Perfect for: living rooms and hallways, bedrooms at night, offices and studios, festive scenting at Christmas
