3M 4255 Half Mask Respirator

A gas mask that protects against paint fumes and particles. The mask has integrated filters of activated carbon which can't be replaced. The life span of the mask depends on which environment it is being used in and how high the concentration of paint fumes is, but you can count on around 30 - 50 hours. Always keep the mask in a clean tightly sealed plastic bag when you're not actively using it, to prolong its life span.
