My company sent me some FFP2 masks, should I need to go to site. Fortunately I haven't but I've tried the masks on and, as has been said in previous threads, they are most uncomfortable to wear and the temptation to continually adjust them is huge, so my thoughts are to get hold of more comfortable masks that could be worn for prolonged periods of time, without the discomfort. Breathing can become quite a challenge too if worn for long periods of time.
Clearly this would reduce the efficacy of the mask but I figure a(ny) mask is better than no mask, especially if you feel the need to touch it all time.
