A conference on the subject of air purification using bipolar ionisation took place at the premises of Aabach TechoAir with the support of the local representative of German Association for Small and Medium-sized Businesses (BVMW). 35 participants with backgrounds in industry and politics took part with great interest. After the meeting there were many stimulating discussions about current subjects, especially the E.Coli cases in Germany which were the topic of the moment. Bipolar ionisation is a particularly effective method of deactivating dangerous germs and microorganisms. Useful contacts were established and several promising projects launched.
