HeiQ Viroblock NPJ03 is one of the world’s first technologies proven effective against SARS-CoV-2 by an independent institution *. SARS-CoV-2 is an enveloped virus from the coronavirus family that causes COVID-19.

The tests have been carried out by HeiQ with the Peter Doherty Institute of Infection and Immunity in Melbourne (Australia).

HeiQ Viroblock is designed to inhibit the growth and persistence of enveloping bacteria and viruses on textile surfaces. It is a unique combination of our proprietary silver technology for anti-germ and antibacterial effect and our vesicle technology for reinforcement (silver chloride biocide ).

HeiQ Viroblock it is effective in minutes

HeiQ Viroblock’s fast mode of action makes this technology unique in destroying harmful enveloped viruses.

Is a Unique combination of HeiQ’s advanced silver technology and a reinforcing vesicle technology. Silver admits silver ions to inhibit bacteria on the surface of the tissue. Vesicle technology depletes the viral membrane, so silver can work more efficiently and quickly to attack the core of the virus.
