Zorin3 years ago+110What is it? The mask (6000 series) itself to which the cartridges are attached? Replacement cartridges for 3M 6000 series masks? Or is it just the shells that clip on to the cartridges with the cotton type particle filters inserted between the cartridge and the shell? I am not sure if this is the case, as there is a discrepancy between the picture, your product description and the reference number.Show in original language (French)1 answer
