The inventors and manufacturers of FRIDA are German entrepreneurs who were also affected by the CORONA pandemic in various areas. Apart from the fact that companies were no longer able to operate successfully, familiar work processes were interrupted, and a host of new challenges arose. New suppliers and subcontractors had to be found, completely banal tasks became unknown problems. In addition, there were economic fears and questions from many employees as to what the future would look like. Along with these problems came family dramas and Corona illnesses with hospitalizations and, tragically, deaths among acquaintances. A word like LOCKDOWN became a spectre and the uncertainty about measures and their sensefulness, permanent media presence of COVID-19 and in addition quarantine for family members, friends and also employees brought all entrepreneurs in many countries and all industries to their limits. But also citizens, customers and of course nursing staff were confronted with a completely new situation, all known strategies for conflict management did not work anymore. FRIDA is supposed to be a successful concept, which makes its contribution to break through fears, but also the ever increasing spiral of bans, bids and distance or hygiene measures – discussions about compulsory vaccination or vaccination dangers, questions about mutations and the future.The acquisition of FRIDA is not only about COVID-19 – we also want to help to better mitigate chains of infection, sources of infection and health-threatening or problematic overlaps when people meet in the future.It is a matter of offering an optimal system also in the future – and nobody knows what awaits us – by using the best currently known systems for "passive" filtration of air by means of HEPA and UV-C light, as well our own development by means of FRIDA DIOMIX for active disinfection of breathing air and additionally the possibility to disinfect surfaces comfortably and regularly.
