Testing by the University of Applied Sciences Northwestern Switzerland
The University of Applied Sciences Northwestern Switzerland studied, among other things. Biow's ozone emissions, among other things. The result: "There was no evidence,that the Biow cleaning device significant amounts of ozone emitted."
Certification by Cere Certifications
The independent testing institute Cere Certifications certified Biow in 2021 according to the standards ISO 9001, ISO 14001 as well as according to the standard for quality requirements for medical devices ISO 13485.
Categorization by GMDN
Categorized as "Therapeutic Air Ionizer" by GMDN (Global Medical Device Nomenclature). The category description is:
An electrically powered device for generating small, biologically active, negatively charged oxygen ions (e.g. reactive oxygen species (ROS)) that are released into the ambient air via a direct air stream to be absorbed into the bloodstream via the lungs and skin, and are intended to have a therapeutic effect for respiratory diseases, muscle function, improved sleep, and/or general health. It comprises an ionization chamber and a controller, and may additionally be configured to generate nitrogen anions, to remove pollutants/nanoparticles from ambient air, and/or to generate laminar airflow. It is intended for use in households and healthcare facilities.
Tested by ALCE
