In hospitals and medical practices doctors and nursing staff work amidst constant exposure to a large number of pathogens. Likewise, in dental practices the aerosols of patients create a drect exposure risk for dentists and dental hygienists. Although disinfecting surfaces and objects is common, disinfecting the air is not. However, aerosols pose a considerable infection risk. The consequence: staff and patients may not be safe.
If too many employees are absent due to illness, this places even more stress on the still active staff further endangering their health. In addition, the situation causes bottlenecks that delay patient care. Furthermore, patients with pre-existing conditions are particularly at risk from germs in the indoor air.
A portion of the air recirculates again and again via the ventilation system. As a result, pathogens spread very quickly throughout the building. Systems with air filters also have a residual risk. HEPA filters of classes H13 and H14 can filter viruses. However, the major disadvantage of filters is that the pathogens are not killed or, in the case of viruses, inactivated. The filters quickly become heavily loaded with active pathogens. Leakage or improper handling of the filters during maintenance and replacement can release these active pathogens.
