Aura, Zefiro, Zenith or Tauer?

Same cold nebulization quality — no water, no heat. The difference is where and how you want to diffuse.

Which one to choose?
Choose Aura if
You want the essentials
You have a small space — bedroom, balcony, study. You want something simple, light and that works both indoors and outdoors, without complications.
Choose Zefiro if
You want to forget about it
You live at home, you want an automatic system that is always active. You set it once via the app and it takes care of itself: it turns off automatically with daylight.
Choose Zenith if
You want to take it with you
You move between different environments — home, office, car. You want something powerful that follows you, not a fixed point.
Choose Tauer if
You want maximum performance
You have large spaces, a terrace, a garden or open environments. You want maximum power with total control.

Small space? Aura. Want automatic? Zefiro. Want flexibility? Zenith. Want the most? Tauer.
Note on coverage: the values indicated are estimates under ideal conditions (closed environments, without drafts). In open spaces, with intense ventilation or high ceilings, performance may vary. For outdoor use, Zenith or Tauer are always recommended, preferably combined with ZanzaRepel body spray.
