Placing the mask
- Opened before touchdown position in the palm; the tapes should thereby extend at hand
Lead mask to his face and pull the lower band over the head back -
Placing the upper band in the amount of the back of the head above the ears -
- Pushing for an optimal fit lock on the harness towards the head
- Nose clip (the blue metal part) Adjust so that the mask in the upper part has no leaks
- Cover for testing the tightness with both hands mask while exhaling vigorously; while a slight pressure should be in the mask build

Purpose
According to declaration FFP2 the mask for working with harmful dusts, mists and smoke, their concentration is allowed to reach 10 times the maximum allowable concentration. The manufacturer recommends it as an ideal mask for demolition work in the woodworking, grinding, at disposal works and construction.
Comfort
Even for a spectacle wearer is to use reasonably comfortable the mask; through the exhalation valve it does not come to fogging. For long periods (the manufacturer recommends maximum 8 hours) but it may already be somewhat uncomfortably warm.
Personal conclusion
I use the mask when emptying bagless vacuum cleaners, leaf vacuums or removing mold spores. In the former case, I use a mask several times; in the latter case (which is rare) only once. The price of 3.99 per piece I think is appropriate, as the mask is more comfortable in use than comparable (slightly cheaper) building products.
