  • 500ml capacity — the largest HETRAS diffuser format; one bottle handles a living room or open-plan space; two bottles sustain the whole home
  • Natural essential oils — fragrance built on a natural oil base, not purely synthetic compounds; the scent behaves differently — warmer and more dimensional as it opens
  • Long-lasting diffusion — slow, consistent release that covers weeks, not days
  • Extra-long rattan reeds — purpose-made reeds longer than industry standard; more surface area above the bottle carries fragrance to breathing height, not just table level; capillary draw keeps consistent diffusion from the full depth of the 500ml bottle
  • 10 in-stock scents now — selected from the broader HETRAS diffuser scent range; use the available scent selector before checkout.
  • Korea-made quality — produced to Korean cosmetic safety standards; CMIT/MIT handling follows HETRAS standard formulation

How long will 500ml last?
Approximately 2–4 months at standard room temperature, depending on ventilation and how many reeds are inserted. More reeds = stronger scent, shorter duration.
Are natural essential oils different from standard fragrance oil?
Yes — natural essential oils are plant-derived and behave differently in diffusion: they tend to be more complex and evolve slightly as the top notes fade. The base scent profile deepens over weeks of use.
Can both bottles be used in the same room?
Yes — in very large spaces (open-plan living areas, loft-style spaces) placing both on opposite ends can maintain even scent coverage. In smaller rooms, one bottle is typically sufficient.
Do the reeds need to be flipped regularly?
Flipping reeds refreshes fragrance intensity. Do this every 1–2 weeks and wipe any drips from the bottle opening immediately.
