According to Moscow Mayor Sergei Sobyanin, infectious disease control, both for Moscow medicine and for others, is one of priority activities. It is essential to upgrade the existing network, maintain it, provide the clinic with new upgraded equipment. In fact, a new environment is being created, and new opportunities for treatment of people suffering from infectious diseases.

May 15, 2020 the Moscow Department of Health purchased air decontamination equipment based on Potok technology for the prevention of infectious diseases, including COVID-19.

Potok units are operated in the following hospitals: Infectious Diseases Hospital № 1, Moscow's Kommunarka hospital № 40, City clinical hospital named after S. S. Yudin, Moscow City Clinical Hospital 52, the Sklifosovsky Research Institute for Emergency Medicine, City Clinical Hospital named after E.O. Mukhina, Infectious Diseases Hospital № 2.

Since humans are the main source of COVID-19, indoor air decontamination is most effective way to reduce the chances of the coronavirus disease.

The air supplied to the rooms of healthcare facilities is decontaminated with the Potok equipment with a microorganism inactivation efficiency at the outlet of at least 99%, followed by high efficiency filtration (similar to filters H11-H14). This ensures the air is microbiologically safe, and as a result: the risk of nosocomial infections decreases, treatment effectiveness increases, the recovery process is accelerated (hospital bed turnover increases).
