Good sitting, good helping

FEATURES
Basically, the mask helps from all occasions when you want to protect his airway. I have, for example - while gardening (lawn, hedge, etc.) tried because I am allergic ever since - even though they may be for not primarily intended. The effect was amazing. No constant nose-blowing in the evening. Up to which substances you can use it if you have doubts, you should then take the safety's sake the product page or manual.

The rearing
The mask is very logically designed. Tightening runs intuitively. But you can also drag the explanatory film well done to this page to rate. That's better than the manual.

WEARING
I was not disturbed them. On the contrary, they gave a compact feel. Positive was that the glasses of the overlying glasses are not shod. Say, she's really flush closed.

THE DURABILITY
The masks have an expiration date. In my case, April 2018, three years. A mask you should use but only for one shift, the one numbered as daily maximum 8 hours. That leaves strictly unfortunately unclear whether they should now be disposed after each use or after 8 hours of use. I think depending on what you have done, you can exhaust the 8 hours even with repeated use. They would then have masks for 80 hours of work.

PRICE-PERFORMANCE
Pro mask you pay just under 3 euros. I have found even after a long search not equal priced with the same alleged quality. Overlooking the useful price-performance ratio is again better.

CONCLUSION
I can not find anything negative. 5 Stars.
