Latest since the outbreak of the COVID-19 pandemic, the importance of healthy air quality has been reaching new levels. Up until the end of 2019, the impact of inadequate indoor air quality has not been of major interest, which is also reflected in the non-availability of air conditioning equipment in many private, public and commercial buildings worldwide.

Workgroups of aerosol scientists, virologists and epidemiologists worldwide have been sharing their knowledge and findings regularly though various communication channels, such as TV news, Social Media, Interviews, position papers (Position paper of the GAeF on understanding the role of aerosol particles in SARS-CoV-2) of how dangerous and impactful the Sars-CoV-2 virus is, how high chances are to catch an infection - especially indoors - and how central of a role high efficiency air filtration solutions play in addition to adhering to existing hygiene and distance rules as well as wearing masks of adequate quality properly.

Based on more than 60 years of cleanroom and operating theater filtration know-how, as well as significant inhouse simulation and testing expertise, MANN+HUMMEL provides state-of-the-art mobile and stationary air purification systems in different designs and configurations.

For buildings with existing heating ventilation and air conditioning (HVAC) systems, MANN+HUMMEL developed a new H13 and H14 ePTFE membrane HEPA filter element, Nanoclass Pro Membrane, which allows the easy upgrade of HVAC systems to HEPA level. The systems will supply cleanroom air quality, having captured more than 99.95% (99.995% at H14) of viruses including their mutations, bacteria and other micro-organisms.

Stylish and Reusable Face Masks

Mask filters and inlays for better COVID-19 contamination control, by MANN+HUMMEL

According to expert findings, wearing a mask is one of the most effective measures to reduce the risk of infection. Many of the available masks do either not provide adequate filtration efficiency or comfort wearing it. Even if the used filter media itself is efficient enough, some of the masks do not close off safely with your cheeks and nose, which allows potentially dangerous bypassing of air.
One of MANN+HUMMEL´s successful internal start-ups, PURAR, has brought mask wearing to a new level. PURAR facemasks are stylish and re-usable facemasks, which have been designed and engineered in Germany. Their washable outer shell closes off smoothly with your face. Replaceable filter elements combined with the perfect fit of the mask help you stay safe and comfortable.
