Respirator life

One shop that I worked at provided respirators with 2 hoses for the filters that tied together around the back of your neck. The filters lasted about 5 times as long. PAPR is the same concept. I did find that there were some problems with the "quality" of the air where the PAPER pulls from. For me it was go back to a respirator or stop eating greasy BBQ burritos od the food truck:poop::confused:
