Shortly before the schools reopen, many classrooms are still not equipped with a mobile air purification device.
This is shown by a survey by WELT AM SONNTAG among the ten most populous German cities.
The responses show that only slightly more than 1,300 such devices have been purchased so far - for over 2,500 schools in these cities.
With the mobile air purifiers, coronaviruses can be filtered out of the room air.
Berlin is a positive example.
In addition to the previous 1200 devices, 2800 units are to be purchased by Easter.
Another 3,500 are planned for the summer.
Dortmund plans to purchase mobile air purification devices for 27 of a total of 154 municipal schools.
Cologne initially ordered 84 mobile air filters for rooms which cannot be ventilated with sufficient shock ventilation or built-in ventilation systems.

Cities like Frankfurt or Hamburg are not introducing mobile air filters across the board and are sometimes leaving it to the schools on their own.
Stuttgart is testing mobile air filters in a pilot project.
Others are initially not planning to use mobile air filter systems - including Essen, Leipzig or Munich.
The Education and Science Union (GEW) is disappointed by the reluctance of those responsible.
"Of course we would have liked the municipalities, as school authorities, to approach the issue of air filter systems more courageously and to make better use of the funds available," said GEW chairman Marlis Tepe WELT AM SONNTAG.
The air filters are an additional measure to improve infection protection, albeit not the central instrument.
The exact effect of the mobile air filter devices has not yet been finally investigated.
Nor are they the only technical way to purify the air.
Some schools already have ventilation systems, some of which can be retrofitted with filters - the authorities in Dortmund, Stuttgart and Cologne point this out.
