The Use of Prosteriel is especially recommended in hospitals where most germs occur. Even if several disinfectant dispensers are attached to the walls. The disinfectant that automatically reaches the hands when touching the door handle means maintaining the sterile environment for the patient without the need for extra effort. A healthy person who has been in the hospital, visiting a relative in the hospital room, or has used the toilet is at a higher risk of infection from germs. For this reason, it is expected that Prosteriel will find widespread use, especially in hospitals.
