Good to know
The box includes the Tower Ultra diffuser, empty 120 ml oil reservoir, IR remote, USB-C cable, power adapter, metal hook, spare nozzle, seal rubber ring, and user manual.

What makes Tower Ultra different from Tower Pro?
Tower Ultra is rechargeable, so it can be used cordlessly after charging. It otherwise follows the same 120 ml tower format with app, IR remote, on-device control, six diffusion levels and three warm-glow modes.
Can I use Tower Ultra without the app?
Yes. Use the included IR remote or the on-device button. The Smart Life app is optional.
What timer settings are available?
The included remote provides 1, 2, 4 and 8-hour timer presets.
How do the six diffusion levels work?
Each level runs for 30 seconds, then pauses for 60, 120, 180, 240, 300 or 360 seconds. Start with Level 1 and adjust gradually for your room and fragrance preference.
What oil should I use?
Use compatible waterless fragrance oil only. Do not add water or oil intended only for a water-tank diffuser. Waterless fragrance oil is sold separately.
How much oil does it hold?
The removable oil reservoir holds up to 120 ml.
Does it add humidity or use heat?
No. Tower Ultra uses waterless cold-air atomization without a water tank, added humidity or heat-based diffusion.
