No personal protective equipment (PPE) and no filter is capable of protecting you 100% against COVID-19. COVID-19 is a new virus that is not yet fully understood. We expressly do not guarantee that our products will protect you against COVID-19. However, if used appropriately with other public health recommendations, they may reduce your risk of receiving or transmitting the disease. It is important to wash your hands frequently, avoid touching your eyes, nose and mouth, as well as avoiding close contact with others who may be infected.
