3M™ Reusable Respirators are designed to be reused many times and a range of spare parts is available to help keep your respirators in good working order and extend the effective service life of the respirator. Replacement speaking diaphragm assemblies are available for some 3M Reusable Full Face Masks and can be fitted by a trained user or a service centre, if the original speaking diaphragm becomes lost or damaged.
