Safemark* Cleanroom Mask

The Safemark 9 inch cleanroom tie string mask is hypo-allergenic and 100% latex free. The masks have an excellent BFE rating. The 9 inch width allows the person to wear the mask under their hood, therefore allowing the blow-by to enter the hood and not the open air. The mask is designed to cover a large area of the face as opposed to the standard 7 inch mask. The string ties are comfortable and easy to tie.
