State of the Art
The Covid 19 pandemic showed that new technologies are needed to protect the health of mankind. One solution is to decrease the infection rates is by reducing and eliminating the number of viruses in the air. Especially indoors this is crucial due to the fact that most of the infections during a pandemic were caused by a high virus load in enclosed areas. A virus is most commonly carried by particles and/or aerosols and an ionization of the carrying airborne particles and a subsequent deposition on a counter electrode will help to reduce the viral load in confined spaces.
Air decontamination in hospitals is currently accomplished by using HEPA filters, which have the disadvantage that they only can filter particles down to a size of approximately 500nm (COVID-19 virus ≤120nm). Additionally, the pollutants separated from the air are only collected in the filter and not inactivated. As a result, there is not only the risk that a proportion of the pollutants cannot be collected at all, but the filter itself may act as nutrient for further pathogen growth and clusters of alive viruses which may be released into the room air again.

Uniqueness of CleanAir
The unique ionizing electrode design of CleanAir (patent pending) is a microphysical system consisting of specially developed polymer fibers and a highly conductive coating which acts as the conducting substrate which may be equipped with additional integrated virucidal precautions (depending on test results). The CleanAir ionizing technology has the advantage that powerful ionization energy can be adapted to the desired values precisely and undesired formation of O3 and NOx, as it occurs during operation of conventional ionizers, does not occur. Airborne pathogens and particles down to the size of atoms are ionized, deposited and subsequently inactivated. Therefore, the installation of CleanAir will set new hygiene and safety standards in medical facilities and other enclosed enviroments.
