Mobile air filtration units are placed in daycare centers and schools

The Federal City of Bonn has awarded the contract for the procurement, installation and maintenance of the mobile air filter units to an appropriate specialist company. The ordered devices are intended for the rooms in day care centers and schools, which, according to the assessment by the administration, correspond to the classification category 2 of the Federal Environment Agency (UBA).

Subject to delivery deadlines, all the devices are to be installed and put into operation in the course of September. Where exactly the air filters will be installed in the individual rooms will be determined by the municipal building management (SGB) in consultation with the daycare centers, schools and the specialist company, as will the order of installation.

For Mayor Katja Dörner, the air filter units are "a sensible interim solution until we have the more sustainable solution of permanently installed supply and exhaust air units. With the air filter units, we improve the air quality in the rooms where the windows can only be tilted, for example."

The crisis management team of the city of Bonn had decided on the procurement and installation of the air filter units at the beginning of August 2021. It had based its decision on the UBA's classification for school and kindergarten rooms, which divides the rooms into three categories. Category 1 rooms can be used without any further technical measures because they are either equipped with a ventilation and air-conditioning system or the windows can be opened wide enough to ventilate the rooms sufficiently. Rooms are classified in category 2 if there is no room air conditioning system or the windows can only be tilted or ventilation flaps with a minimum cross-section are present. Category 3 rooms cannot be ventilated; they will not be used until further notice.

The equipment with the air filtration devices is to be only a temporary solution. In the long term, the affected rooms are to be equipped with a permanent supply and exhaust air system. The administration will take advantage of funding opportunities announced by the federal and state governments for both.
