“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.”​

For club managers, the current situation is even more difficult than for businesses in other industries. In order for clubs to be allowed to open - and stay open - strict hygiene regulations must be observed. Since September 2021, Club Freiraum in Offenburg, Germany, has been offering its guests and team an extended protection concept: Seven OurAir SQ 2500 air purifiers ensure that the virus-laden aerosol load in the indoor area is drastically reduced on a permanent basis. The devices fit very well in the interior of the Freiraum and offer additional protection during the club visit besides the official hygiene concept.​
