German supermarket trials UV-C air purifiers

A small supermarket in Hamburg, Germany is trialing UV-C purifiers as one possible method its larger group might use to remove coronavirus that could be present in the air.  

The branch of the national Edeka chain has also deployed a UV-C disinfection chamber to clean handheld scanners that employees share.

The 14,538-ft2 Edeka Clausen store in Hamburg has mounted 31 Philips UV-C disinfection fixtures from Signify, at between 10.5 ft and 11.5 ft high and pointing them outwards, parallel to the floor. The purifiers use conventional mercury vapor technology, not LED, to generate the ultraviolet radiation.
