The BUFF® Filter Maks and the BUFF® Filter Tube act, in a way, as a barrier against the spread of COVID-19 by minimizing the diffusion of saliva droplets that we expel when we talk or laugh. There is growing evidence that covering one's nose and mouth with cloth helps prevent people from transmitting the virus to others, especially when used within the same community.
The BUFF® Filter Mask and the BUFF® Filter Tube are certified according to CWA 17553:2020 and UNE 0065:2020. The filters meet the standards for surgical masks EN 14683:2019 + AC in relation to bacterial filtration efficiency (BFE%) and differential pressure (Pa/cm²) (air permeability), obtaining a type I and II classification. However, neither the BUFF® Filter Mask nor the BUFF® Filter Tube are certified as medical or personal protective equipment. They are not designed to be used by healthcare professionals, occupational professionals, or as any other protective device to protect against infection.
