General information:

Coronavirus (2019-nCov)

The disease was first identified in December 2019 in Wuhan, the capital of China’s Hubei province, and has since spread globally, resulting in the ongoing 2019–20 coronavirus pandemic.

The virus is mainly spread during close contact and by small droplets produced when those infected coughs, sneeze or talk. These droplets may also be produced during breathing and can spread through the air over small distances, especially in non-ventilated rooms, indoors. People may also become infected by touching a contaminated surface and then their face. For this reason, masks are the best products to slow down the spread of the virus!

Our mask is a new generation, another category mask, with tested viral and bacterial filters. Our mask is been tested as PPE and is categorized after EN 149:2001+A1:2009 respiratory protective devices, as a cat. III equipment, as special COVID-19 protective equipment.
