Air cleaning devices filter the smallest particles from the room air. Standardised tests are used to measure how many particles of a defined size are removed from the room air. MEDIACC supports manufacturers of such air purification devices in these tests. Result: From 5.000.000 particles (also in virus size!) only 20-30 particles get into the ambient air when using the air filter – practically nothing. Does this make personal contacts possible again? Yes! The certified effectiveness of this filter enables safe contact in areas where personal meetings are necessary. We are proud to provide another building block in the fight against the pandemic and return to normality with personal meetings!
