Our Scentech diffuser has a standard coverage of 50 m². In many cases it's even more, up to 75 m², depending on the scent and intensity you use.
Scent distribution works via cold air diffusion technology, meaning the scent spreads very evenly through the room. In principle, the scent always reaches the whole room, provided there's good air circulation.
Still, scent strength can differ per situation. That's not down to the device, but to the scent you've chosen and your personal sensitivity to scent.
Strong scents like Amber Glow, Dark Elixir, Endless Path and Tea Whisper are easy to smell even on low intensity, even in larger rooms.
Subtler scents like Calming Lavender, Pure Blossom, Garden Mist and Wild Blossom are milder. If you have a less sensitive nose, these scents might give you the impression the device has lower coverage. But the scent is there, it's just more refined and softer.
These subtler scents are actually a great fit for people who are sensitive to scent.
In short: the diffuser covers your whole room in principle. Want the scent to be present more strongly? Choose a more powerful scent or turn the intensity up a bit in the app.
