The 3M™ P3 R Particulate Filters 6035 provide protection against solid and oil/liquid particles. The filter media is encapsulated in a robust plastic case that allows the filters to wiped clean. Suitable for use with 3M™ Reusable Respirators featuring the Bayonet filter connection system: 3M™ Reusable Full Facepiece 6000 Series, 3M™ Reusable Half Facepiece 7500 Series, 3M™ Reusable Half Facepiece 6500 QL Series and 3M™ Reusable Halfpiece 6000 Series. For P3 R breathing protection against solid and liquid particles, and with more surface area than many standard filters, use 3M™ Particulate Filters 6035. The surface area is 1.8 x larger than 3M™ Particulate Filter 2000 Series filters and can potentially increase service life in some applications.
