How the indoor climate can reduce the risk of infection for employees.

In workplaces with poorly configured ventilation and air conditioning systems, not only will you find people and machinery, but also large quantities of viruses and bacteria – both in the air and on surfaces. Recent studies show that the survival time of viruses is significantly influenced by the level of humidity. If the room air is too dry, viruses remain infectious much longer than at average relative humidity. If the indoor climate is not right, employees are exposed to a high risk of infection.

It is therefore all the more important to consistently monitor the indoor air quality in order to prevent possible sickness, particularly during times like these. On this page you will find everything you need to know about this topic – the scientific background, suitable measuring technology and even a practical guide.
