The 3M™ 8835 Particulate Respirator Valved FFP3 (Pack of 5) has exceptional comfort because of its lightweight, off the-face design - its advanced soft facepiece with sealing ring covers a large surface area, providing maximum filtration, but minimising the build-up of hot air inside the facepiece. Also equipped with an exhalation valve to reduce moisture build-up in certain work conditions, plus 4-point adjustable straps and adjustable nose clip to ensure a comfortable fit.
