frequently asked
what does onyx smell like?
clean, bright and island-inspired — light and refreshing rather than sweet or smoky. the most easy-going scent in the range.
how big is it, and how long does it last?
500ml. the bottle is 170mm tall and 80mm square, with 375mm reeds. as a guide, around three to four months.
where does it work best?
bathrooms, bedrooms, kitchens and hallways — anywhere you want the air to feel fresh rather than warm. for open-plan rooms, take the 2200ml extra large.
how do i set the reeds up?
put all the reeds in, leave them an hour or two to draw the oil up, then turn them over once. after that, flip them every week or two to refresh the scent — that's all it needs.
wash your hands after handling the reeds, and don't put used reeds back in the bottle.
can i make it stronger, or make it last longer?
yes — it's controlled by the reeds. more reeds means a stronger scent that gets through the oil faster; fewer reeds means something subtler that lasts longer. start with about half and add more if you want more.
where's the best place to put it?
somewhere with a little air movement — a hallway, a landing, near a doorway — rather than a still corner. keep it out of direct sunlight and away from radiators, which will burn through the oil quickly.
stand it on a coaster or tray. fragrance oil can mark wood, painted surfaces and polished stone if it drips or is knocked.
is it safe around children and pets?
keep it out of reach of children and animals, and don't put it somewhere it can be knocked over. the oil is an irritant if it's swallowed, or if it gets on skin or in eyes.
can i return it if i don't like the scent?
only if it's still sealed. once a diffuser has been opened we can't take it back for hygiene and safety reasons, unless it's faulty. unopened, you have 14 days from delivery — see make a return.
how quickly will it arrive?
orders are packed and dispatched within 2–3 working days. uk delivery is free on orders of £40 or more and £3.95 under, or choose express at checkout for £5.95. extra large diffusers always go free.
