In packages of ten dust masks the security level FFP2 are packed in a cardboard box. For detailed information on the use and correct customizing contained in the manual. The purpose of this mask is to protect the user from inhaling dust produced for example during renovation work in and around the house. As I understand it, these masks are suitable for both the private as well as for professional use.
As for me, so I need a respirator, because it was in the house where I live refurbished recently. For now accumulating cleaning, it is essential to wear a reliable protection to avoid breathing in the fine dust.
By applying the mask I got along well. Thanks to the valve, which is located in the nose, breathing in and out is not a problem. Important in this context is that the mask stays dry through the valve, even if you are wearing a long time and during which some physical activity. I had the feeling that, were safely protected my airway before the fine dust created by the sanding of wooden frame. Of course this is a subjective impression, which is, however, underpinned by the fact that I suffer from very sensitive nasal mucosa, which react immediately to external irritations.
All in all, I recommend this dust masks from Dräger, because there is in my view no complaints.
