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. Our particulate filters offer low breathing resistance and good balance when connected to your mask and are designed to optimise your field of vision. A sprung mechanism allows the wearer to perform a quick and easy face seal check every time the filter is used. They can be clicked into place quickly and easily, and they can be used with any 3M™ Reusable Masks that feature a bayonet-style connection. The hard case is ideal for harsh environments where easy decontamination and protection is needed
