High quality Air Filtration for improved Indoor Air Quality

The quality of the air we breathe has never been under such a high public focus as it is today during the Covid19 pandemic. But society needs to be aware that air may not only contain infectious virus but also can contain other harmful particles and gases like bacteria, allergens, toxic gases, VOCs or just small particles which can be harmful already just because of their small size. Air is the most important, but also most underestimated consumable. We take much care about the food we eat or the beverages we drink, but too little about the air we breathe. Humans can survive without food for a few weeks, without drinking for a few days, but without breathing, just a few minutes. Air handling units using high quality and efficient fine filters and by regarding specific advice given for the pandemic times do reduce the virus concentration in buildings. Together with other measures like keeping distance and wearing face masks, this can reduce the infection risk significantly. But even beyond the pandemic, all technologies are available to ensure healthy air in our homes and buildings. They “just” need to be designed, installed, operated, and maintained in a proper and efficient way to ensure the quality of the air we breathe. Thereby, a holistic approach is essential. None of the components of a building ventilation system on its own can ensure good air quality and minimum energy consumption at the same time. This can only be ensured if all components, the whole building, including its occupants, work smoothly together like a well-oiled machine.
