Effec ve filtra on for A surgical mask is not designed nor intended to protect the user. The splash resistant mask offers splash resistance but does NOT provide protec on against airborne bacteria. However, it will protect individual around you. Ÿ The BFE is the effienciency of a surgical mask in retaining aerosol drops containing bacteria. It indicates how many par cles are retained by the surgical mask. This is directly related to the amount of bacteria released into the surrounding air through the mask. The higher the BFE percentage, the be er the pa ent is protected against par cles from the medical staff. Ÿ
