100 percent for clean drinking water

MANN+HUMMEL fully acquires Seccua Holding AG and thus strengthens its activities in the field of water filtration

Ludwigsburg/Steingaden, September 10, 2021 - The MANN+HUMMEL Group has fully acquired Seccua Holding AG as of September 7, 2021. After investing in a strategic partnership back in 2019, the Ludwigsburg-based filtration specialists have now acquired all shares of the company.

Seccua specializes in the manufacture of ultrafiltration membranes. These reduce viruses, bacteria, parasites and turbidity in water - without chemical or ultraviolet treatment. Public utilities, municipalities, hospitals, food and beverage manufacturers, and increasingly private households rely on Seccua's filtration solutions for drinking water treatment.

"For years, MANN+HUMMEL has been continuously expanding its portfolio in the areas of water and air filtration. We are convinced of the growing importance of the drinking water market. By fully acquiring Seccua, we will continue to grow in this area," said Fua Nipah, President and General Manager of the MANN+HUMMEL Group's Life Sciences & Environment Business Unit.

Founder and former Chairman of the Executive Board Michael Hank and MANN+HUMMEL jointly agreed that he will continue to support Seccua as an independent advisor. The two remaining board members Martin Kunze and Daniel Haußmann will jointly lead the business on an interim basis.


MANN+HUMMEL is a leading global company in filtration technology. Under its two business units Transportation and Life Sciences & Environment, the Ludwigsburg-based Group develops intelligent solutions that enable cleaner mobility, cleaner air and cleaner water. Thus, the company makes an important contribution to a clean earth and the sustainable use of limited resources. In 2020, over 21,000 employees at more than 80 locations generated a turnover of EUR 3.8 billion.

Among the solutions are filter media and simulation technologies, liquid filters, air filtration and intake systems for various mobility and industrial applications, and membrane technologies for municipal and industrial water and wastewater treatment and use in sensitive process applications such as food manufacturing or biotechnology. Furthermore, the family-owned company founded in 1941 offers air and molecular filtration technologies for building filtration as well as for industrial applications and cleanrooms. These are used, for example, in power generation, microelectronics or operating rooms. Stationary and mobile air purifiers for indoor, semi-open spaces and outdoor areas complete the holistic approach to clean air. Depending on the area of application, they filter viruses, free allergens, bacteria or fine dust and nitrogen oxides from the ambient air.
