CLEAN MOBILITY
MANN-FILTER has its focus on the future Millions of people around the world are suffering from the effects of polluted air, not only outdoors in spaces with a lot of traffic, but also inside vehicles. It is therefore becoming essential to improve air quality by reducing particulate matter and harmful gasses. With its latest innovation in cabin air filtration, global filtration expert MANN+HUMMEL says it is concentrating on a particle size that is becoming increasingly important – so-called ultra-fine particles (less than 0.1 micrometre). These can get particularly deep into the human body and cause harmful damage there. The World Health Organization (WHO) is also paying particular attention to ultra-fine particles and in its latest air quality guideline has called for this particle size to be included in routine measurements. Regardless of the drive system, cabin air filters play a major role in providing drivers and occupants with clean and healthy air. In electric vehicles, there is also a trend toward improving air quality through multi-stage filter systems.
The future of cabin air filtration: multi-stage HEPA filter systems MANN+HUMMEL has developed HEPA filter systems to effectively protect people from these microscopic impurities. The abbreviation HEPA stands for High Efficiency Particulate Air. It is not a protected term, so special care must be taken here.

The addition of “in accordance with DIN EN 1822 and ISO 29463” indicates whether a filter actually meets the high requirements of European and international standards. “Our filter media meet these requirements,” MANN+HUMMEL Business Development Manager Cabin Air Quality, Christiane Michel, said. “Our multi-stage cabin air filter systems with highly efficient HEPA filters offer protection through clean room quality air filtration, as is also the case in operating rooms, for example. “Depending on the HEPA class, at least 99.95 percent of the particles are reliably removed
from the air, including harmful bacteria, viruses and other microorganisms, even the previously mentioned ultra-fine particles. “These are so small that they can easily penetrate into the bloodstream, cause severe damage to organs and be carcinogenic. “We now know that more than 90 percent of the particles in the air are ultra-fine particles. Whether they are safe or not depends on their source and chemical composition.” MANN+HUMMEL uses the HEPA filter as part of a three-stage system along with a prefilter and a cabin air filter.
