Accordingly, about 1200 mobile air purification devices will be procured for schools whose classrooms can only be ventilated with difficulty due to the structural situation. A total of 4.5 million euros has been earmarked for the purchase. These devices can greatly reduce the risk of infection by aerosols for employees and students in rooms without sufficient ventilation and thus further spread of Covid-19.

Thestate of Brandenburg has not yet decided on its own funding programmes:

The funding is intended exclusively for rooms with limited ventilation options in primary schools (children under 12) and daycare centres.

As of 16.07:
Senator for Children and Education Sascha Karolin Aulepp: "Over 60 per cent of schools are equipped with air filters".

The schools could and can order the devices via a Bremen internal online ordering system after the application has been approved. During installation, the schools were supported by caretakers, school administrators and, if necessary, specialist companies. The mobile air purification devices are financed from the "Bremen Fund" (total volume 1.2 billion euros) via the budget framework for the procurement of pandemic-related items. This was increased by 27.8 million euros to 48.6 million euros by resolution of the Senate on 18 May 2021. The continued procurement of mobile air purification devices as a supplement to ventilation is thus financially secured and still possible upon request.
