The BUFF® Filter Mask and the BUFF® Filter Tube are the only BUFF® products accredited in a laboratory. Our multifunctional neck gaiters perfectly cover the face (nose, mouth, chin and neck) and can help you not to touch your nose and mouth so often. Direct or indirect contact with these areas poses a risk of transmission of COVID-19 by transferring the virus from the hand to the mouth, nose or eyes after touching a contaminated surface. However, BUFF® multifunctional neck gaiters will not protect you against infection or prevent you from infecting others, as they are not certified as medical or personal protective equipment.
