This line of respirators has been conceived to improve the worker’s hygiene and to increase handiness. Thanks to its vertical folding shape it grants a wide field of view. The single packaging improves the worker’s hygiene by avoiding any contact with harmful substances before the use. The sliding elastic bands have been studied to hang up the mask around the neck when the respirator is not used without any inconvenience. There are no exposed metal parts. Materials are long lasting and avoid the collapse in humid environments.
