How many users can I define on my Spirohome Personal?

More than one user account can be paired with a single Spirohome Personal device, however, the device will only pair with one user account at any given time. The Spirohome Personal should be used by a single user, and a new user must connect their own user account to the device. Furthermore, mouthpieces should be replaced and disinfection of the device must be performed (for more information in user manual).
