There are a lot of complaints in the reviews stating that the masks are to small, the earloops are to short, there is to much tension, uncomfortable to wear, etc., etc. I believe that all these commentators do not have any good understanding as to what this mask is supposed to do: To be effective and protect you against contamination, the mask must have a tight seal at the face surrounding your mouth and nose. This is effected by keeping the loops short, so that there is sufficient tension to keep the border of the mask pressed against your face. Of course, this is not super comfortable, and you ears will flap, making you look like of one of the Walt Disney seven dwarfs. But once you put it on this way, you will realize that the mask does indeed make a pretty good seal, protecting you much better against anything in the air than an ordinary paper mask. On top, you have the increased filtration capacity. Of course, the design of a „real“ N95 mask is better, since there loops are designed to wrap around the entire head, which relieves some of the tension, and provides also for a better fit, but in comparison, you will realize that also an N95 mask is not that comfortable. So all in all, you need to take that into account, when complaining about the size, etc. of the mask. It’s about the protection, not comfort. I have a pretty large head, and believe that in light of the above, the mask is properly sized for large heads. Of course, I have no idea whether the purported feature („95% filter quota) is real, but what I can state is that the mask makes indeed a good seal, so I am optimistic that it and its many variants are currently the best available mask alternative. So far, this particular brand did for me best in not fogging my glasses (or only comparably much less fog), and it also is the most neutral smelling mask I ever got up to now.
