* These masks are not medical devices or personal protective equipment (PPE). They are for personal use and are not intended for use by health care professionals or for use in hospitals or health care facilities. These face masks should not be used in any surgical setting or where significant exposure to liquid, bodily or other hazardous fluids may be expected, a clinical setting where the infection risk level through inhalation exposure is high, the presence of a high intensity heat source or flammable gas.

** There are seven types of human coronavirus: 229E and COVID-19 are two of them. The different types of coronaviruses are highly similar in their membrane structure. The membrane is what our vesicle and silver technology in HeiQ Viroblock NPJ03 targets in order to achieve reduction in the viruses’ infectivity. Our technology has also been tested against Influenza types H1N1, H5N1, H7N9, and Respiratory Syncytial Virus (RSV) and demonstrated significantly improved reduction of virus infectivity. Regarding the efficacy of our technology on COVID-19, a direct test has not yet been carried out.
