As long as I breathe, I can also work.

My father worked before his retirement in a chemical plant and could buy good respirators on the local factory sales, whose quality has never been achieved by the goods in the local hardware store. With the good and precise fit the 3M Aura the original claim is however quite close, so reminiscent, at least in some areas of professional industrial products.

However, potential meets weaknesses. On one side stands a good protective property, the firm grip and pleasant wearing comfort, but also the negative side effects can not be completely overlooked. First, the mask exhales pretty artificial, so should not be used immediately, but at least briefly to fresh air. The processing corresponds only partly to the relatively high price levels, because the rather simple knitted, double rubber bands are laterally just tacked, neither glued nor sewn.

The system-related start-up of glasses with glasses and slight internal moisture of the mask are owed inevitable concomitants and the own breath, here I would reach during strenuous work on contact lenses and breathe in irregular intervals without a mask through.

Conclusion: Solid, although not perfect, respiratory protection, which also supports for hours and continuous operation without losing quality.
