The handling is easy: remove mask, take the valve to the front of the best in his left hand. then first over backwards cause the lower rubber over the head. Then put the mask on the nose and mouth, and then pull the second rubber, and placed at the back (near the top). Then adjust to this second rubber, the length at will. Then you can the nose clip as desired in bringing "fit", finished.
Well, no dust mask is for me personally a "favorite mask", because there is something sitting that one is not just used as an occasional handyman properly. But of the masks that I have used so far in flexing or cutting concrete bricks or concrete slabs or grinding with the eccentric sander, this is so far the best. The others were simpler models without "purge valve".
When it was really hot outside, I have also performed such work ever without a mask. During the subsequent cleaning of the nose, the handkerchief was then "pitch black" ... The masks came at the right time. I have used it, and our living room chairs freed with the sander of black and red paint. For the dust mask was very helpful.
Good seat, fair price, "nose clean" 5 stars for the Dräger X-plore dust mask.
