The 3M Robust Comfort Half Mask was designed with dirty and hard workplaces in mind. It is available with a 3M Quick-Release - Drop-Down mechanism. The 3M Quick-Release system enables the mask to be put on and taken off quickly when entering or leaving the danger zone without having to remove the helmet or face shield. The mask is available in three sizes and is equipped with the 3M bayonet click filter connection. This allows the use of a wide range of 3M filters to protect against gases, vapours and particles, depending on the user's needs.
