Sustainable Air Filtration for Improved Indoor Air Quality

Updated: Oct 9, 2022

Join Dr. Thomas Caesar, Director Global Filter Engineering, Freudenberg Filtration Technologies, at the WFI 2022 Annual Conference on December 6, 2022. He will be addressing some of the recent developments in advanced filtration technologies for indoor air quality.

Sustainable Air Filtration for Improved Indoor Air Quality

During the COVID-19 pandemic, public awareness of air quality has increased. Besides infectious viruses, the air may contain other harmful particles and gases like bacteria, allergens, toxic gases, VOCs, or other small particles that can already be harmful because of their small size. To ensure high indoor air quality, filtration of the building intake air and the recirculated air is essential. After almost three years of Corona, other topics like the dramatically rising energy cost and climate change have also regained awareness. Air filtration implies flow resistance and requires energy to overcome this resistance. Therefore, the need for improved indoor air quality might be seen as a contradiction to the imperative to save energy and reduce CO2 emissions. In fact, it is a classical optimization task in engineering. Also, sustainability is not only ecological sustainability. There is also social sustainability, which implies the health and safety aspects. Hence, high-quality, energy-efficient filtration is, per se, sustainable, helping to sustain the healthiest environment by using a minimum of energy.

Eurovent, the European Industry Association for Indoor Climate, Process Cooling, and Food Cold Chain Technologies, has developed guidelines that give filtration recommendations by linking outdoor air conditions to application-specific minimum supply air conditions. The outdoor air, as well as the supply air concentrations for fine dust, are based on the WHO recommendations. In addition to the filter efficiency recommendations, an energy efficiency classification system is offered by Eurovent, allowing the user to choose the system with the most significant handprint at the lowest footprint.
