ViriMASK has developed a face mask designed to provide maximum protection against micron-sized particles. Its filters retain inhaled and exhaled particles larger than 0.1 microns, such as bacteria and viruses, exhaled aerosols, and environmental aerosols. The filters retention capability coupled with the ViriMASKs lack of an exhalation valve prevents the spread of infection back into the environment. ViriMASKs full-face design straps around the head, covering the eyes with a see-through visor and the nose and mouth with a filtering mechanism. It is completely sealed to outside air penetration, preventing infection and contamination through the eyes. The mask also has low airflow resistance, which allows more comfortable breathing and minimal skin pressure for extended wear, and can be washed and disinfected. ViriMASK is a subsidiary of Oneg HaKarmel Ltd.
