The 3M respirator does not happen.
I can adjust the mask perfectly well on my little face. The rubber bands are sufficiently narrow so that the mask nicely firm but not too tight.
The fogging of glasses takes place in exceptional cases still held but no longer as strong and as often as with a commercial Surgical Mask.
The mask is really good to be transported packaged, so that I can carry with me always, and if necessary have to hand.
I think she wears much more pleasant than anything I've tasted.
Of course, they can smells oppose at an autopsy little, this in spite of the filter even under the mask already still clearly perceptible.
Despite the high price of 5 masks I am absolutely convinced, and will from now on take up this mask, rather than meddling with Surgical Mask and to have a fogged glasses.
Very practical and sophisticated!
