My hobby is the wood painting. For this I saw me cope my wooden parts and then must grind them afterwards, before I can then paint with a Brandmalkolben. As my respiratory system, caused by some are pneumonia, not in top form, I have to protect wood against fine dust while working.
For this, I had bought more favorable dust masks at the hardware store. Also brand but it is cheaper than that of Dräger. Having now had the dust masks from Dräger during my work on, I have to say ... it's a huge difference. They are very easy to set up and adjust, fit well and close everything off nicely. So good that not even my glasses fog breathing. Whether it has brought what one sees afterwards nice because if you with fine dust that is created when sanding or sawing, inhales, then you always have accordingly a thing or two in the nose. Not with the mask Dräger more.
Breathing in the mask is a bit more difficult than without a mask but really just a tiny bit. Should use it only once for a maximum of 8 hours and discard it. For Beard carrier it is not necessarily appropriate. It also protects against infectious agents but only to a small extent. For this, you should prefer to buy other masks that are specially. After the expiry date you should not use it. My masks hold until 04.2018. The date can be found on the packaging.
I like the dust masks from Dräger really very good. With them, I can indulge my hobby beautiful without making me worry about possibly polluted airways. Find ich super.
