Darmstadt: 400 new air filters for school and day care rooms

Darmstadt only purchases mobile devices for daycare centers, elementary schools and special needs schools. In addition, devices for measuring the carbon dioxide content are to be set up.

The handling is quite simple: the power plug has to be pushed into the socket and the device switched on with a switch, and the small air filter is already in operation. To the delight of headmistress Katharina Rothkirch, mobile air filter devices have also been set up in several classrooms at the Heinrich Heine School in Darmstadt’s postal settlement this week.

After 280 of these devices had already been set up in the past winter months in classrooms and childcare rooms, which are difficult to ventilate, the city has now purchased a further 400 devices. However, half of the filters ordered should only be used in elementary and special schools, the other half in day-care centers.

Lord Mayor and Head of School Jochen Partsch (Greens) justified this limitation on Thursday with the fact that there have not yet been any approved vaccines for children under the age of twelve against the Covid-19 disease caused by the Sars-CoV-2 coronavirus. However, devices for measuring the carbon dioxide content should be set up where such mobile air filter devices will not be located in order to support the correct ventilation of the rooms. The in-house property management of the City of Darmstadt (IDA) is responsible for equipping the schools and daycare centers.


Mobile air filter devices are intended to support window ventilation where there are no centrally installed ventilation systems or decentralized ventilation systems.

The decentralized systems , which are about the size of a refrigerator, are to be installed in 11 of 18 Darmstadt primary schools. In a pilot project, the city wants to equip the Wilhelm-Busch, Georg-August-Zinn and Ludwig-Schwamb schools with such decentralized systems without federal funding. jjo

In addition, with financial support from the federal government, the city wants to gradually install so-called air conditioning systems in the Darmstadt schools in order to continuously supply the classrooms with fresh air.

Mayor Partsch criticized that the federal government had launched the funding program “much too late”. Because the approval procedure takes some time, the city wants to equip three schools with new ventilation technology in a pilot project in September.

According to IDA operations manager René Kirch, 167 classrooms can be considered for the installation of the systems, for which funding applications for the corresponding program have also been submitted. In the day care centers, too, it is currently being examined at which points the use of ventilation and air conditioning systems would make sense.

With the faster to procure and cheaper mobile air filter devices, the air quality should be improved by filtering and the virus and germ load should be reduced. The best way to reduce the viral load, however, is the exchange of air by supplying fresh air, which is also essential when using mobile air filter devices, said OB Partsch. Wherever there are no central ventilation systems, decentralized ventilation devices should be installed.
