How do reed diffusers work, and how long do they last?
Short answerA reed diffuser is flameless: the rattan reeds draw scented oil up from the bottle by capillary action and release it into the air as it evaporates. Flip the reeds every few days to refresh the scent. A set typically lasts about 1–3 months depending on bottle size, reed count and room conditions.
Reed diffusers are the quiet, flame-free way to scent a room continuously. There's no heat or electricity — just physics.
How they work
- Capillary action: the porous rattan reeds wick the fragrance oil up from the bottle.
- Evaporation: the oil reaches the top of the reeds and diffuses gently into the air.
- Flip to refresh: turning the reeds every 3–7 days re-saturates them and revives the scent.
How long they last
Most sets last roughly 1–3 months. More reeds and a warm, airy room mean a stronger scent but faster use; fewer reeds make a bottle last longer. Keep them out of direct draughts and sun. Neoi's MOMO reed diffuser is part of our aromatherapy collection — a calm, continuous alternative to a water or nebulizing diffuser.
