Proof of effectiveness

Reducing the risk of infection with OurAir Purifiers with HEPA Filters

Scientifically Proven Effectiveness

A study by the Karlsruhe Institute of Technology confirms the effectiveness of the OurAir TK 850

It is now known that the Coronavirus (COVID-19) is mainly spread through aerosols in the air. Aerosols are tiny droplets that are emitted into the ambient air through breathing and speaking, and can then spread throughout the room. In order to reduce the concentration of viruses in the air, it is necessary to either replace or purify the air. Wherever effective ventilation is not possible, antiviral air purifiers come into play. But how effective are they really? Do they help to reduce the aerosol levels?

The KIT (Karlsruhe Institute of Technology) has conducted a study and confirmed that the OurAir TK 850 room air purifier significantly reduces the number of particles in the room and thus contributes to reducing the risk of infection. Read more about the scientific study.

BBUG Business Talk

Conference 21.09.-02.10.2020

"MANN+HUMMEL saved our conference. It was a challenge holding a two week conference with 50 attendants in a landmarked palace during the covid pandemic. The very handy, low noise effective air cleaners from MANN+HUMMEL  – straight from the production line – were a great relief for us and gave our attendants a feeling of security."
