I bought it because it was a good price. It's nice to have two wires, but it's a drawback to the side. It's a bit less quality than the fine dust masks we usually sell in our country. I go out and get rid of it often.
But rather than having a pore next to you. The dust does not come in close enough.
I bought this one only when I packed it individually, but I recommend it at home. When you go out, you draw one by one.
