How to choose the right diffuser
Diffuser types compared by room size, intensity and the way you use them.

A diffuser isn't just a source of scent – it's also an object you'll see every day. Before you choose, think about three things: how large a space you want to fragrance, how strong you like your scent and how much care you want to give it.
Ultrasonic diffuser
You pour water into the tank and add a few drops of essence, and the diffuser turns it into a fine, cool mist. The scent is subtle and the device runs quietly, so it suits a bedroom, a study or a bedside table. SORA mini, for example, has a 100 ml tank, runs for up to 4 hours and is powered via USB-C.
Nebulising diffuser
It works without water, diffusing pure essence straight from the bottle. The scent is stronger and lingers in the room for longer, so it suits living rooms and larger spaces. NEBULA handles rooms of up to 60 m². Bear in mind that it uses more essence than an ultrasonic diffuser.
Reed diffuser
It needs no electricity and no attention. Rattan reeds draw up the fragrance and release it continuously and unobtrusively – ideal for a hallway, bathroom or corridor. A 100 ml bottle lasts roughly 6–8 weeks. To boost the scent for a while, flip the reeds. Choose from our reed diffusers.
Aroma burner
A tea light warms scented wax or essence with a little water. Besides the scent, it brings the soft light of a flame, so it is best suited to evenings. Don't leave an aroma burner such as KÁMEN burning unattended.
Which one to choose?
- Bedroom, study, travel: an ultrasonic diffuser.
- Living room and larger spaces: a nebulising diffuser.
- Hallway and bathroom, hassle-free: a reed diffuser.
- An evening mood by the light of a flame: an aroma burner.
You'll find every type in our collection.
