Nevertheless, it is in my opinion the most popular disposable half mask, and for good reason. They can be used in many ways and adjust very well and staff.
In addition, you can use them for a long time, always assuming that safety measures are adhered to.
I'll soon be back, cover my bottom. The old PVC covering stinks and is certainly polluted.
But even fine dust and mold spores may be borne by the mask from his body well.
So why "only" 4 stars? Because there is a mask that suits me more. The half mask body size M 6000 Series, low maintenance, 1 piece tells a little more about me. It is a little softer, which of course means more plasticizers in plastic, it wears comfortable and is not a disposable product. Of course, this does NOT mean that you this half-mask 3M 4255 can be used only once. It primarily means that you have to discard if the filters are full. The respective Sicherheitsmasnahmen please refer to the instruction manual.
If one firm sets the 3M 4255 and carries a long time, welts are emerging in the face. However, disappear after a while. Well, the resealable aluminum "bag", so no dust or other comes to the mask.
Thus, the 3M Half Mask 4255 is not a bad choice.
