Following the recognition that COVID-19 is acquired by inhalation of particles in the air containing SARS-CoV-2 virus, Lidl U.S. will install high-efficiency air filtration rated at MERV 13 in all U.S. stores by the end of this year.

Johannes Fieber, U.S. CEO of Lidl stated, "customers and team members in Lidl stores can breathe easier knowing we have an added layer of protection against COVID-19". 

Maryland Governor Larry Hogan noted "as we remain vigilant in combat against COVID-19 it is more important than ever for businesses to offer a clean and healthy environment".

Lidl has raised the bar for protection, and it is inevitable that other supermarkets and grocery stores will follow their lead to maintain customer goodwill and to avoid litigation.

Stores could also consider installation of dry-hydrogen generators that are capable of destroying viruses on suspended particles in the air of areas where customers and staff congregate despite social distancing
