A Safety-Compliant Power Supply for Mobile Air Purifiers:

8 June 2022

Out of the Box: Air Purification

The influence of indoor air on human health has been known for a long time; it also became a key issue in the discussion about (re)opening schools during the COVID-19 pandemic. By rapidly developing mobile air purification devices, Miele, a family-owned company, hoped to help many families by improving health and restoring a degree of normalcy to their everyday lives. Thanks in part to outstanding collaboration with WAGO, the project has been a complete success.

The significance of infectious aerosols in connection with COVID-19 and the debate on atmospheric particulate limits have once again focused our attention on the huge effect air quality has on our health. Adults breathe more than 20,000 times a day, taking between one half and three liters of air into their lungs each time. These organs are directly coupled with the outside world, so several protective mechanisms exist to ensure that respiration lets as few pollutants as possible into our bodies. But if the pollution level remains constantly excessive, this stress hurts our health, leading to diseases such as bronchial asthma or COPD (chronic obstructive pulmonary disease). Such chronic respiratory diseases are among the top causes of death worldwide. These are very good reasons to be concerned with air pollution control and air purification.

This concern was shared by division of Miele & Cie KG specializing in the manufacture of commercial products: “Even just our experience with clothes dryers has given Miele decades of know-how about blowers and filters. And we’re already using high-performance filters in our medical products too,” explains Bernd Taphorn, the development engineer at Miele responsible for the entire electrical design of the air purifier project. “We wanted to get our mobile air purifiers on the market as quickly as possible, while maintaining our high standards, in order to restore a bit of normalcy to people’s lives in these unprecedented times.”
