not worth the price
The shape accommodates the face fairly well, but the filter is hard to get in and out, and it gets wrinkled inside the slit. The instruction says that the filter lasts for a while, but we should wash the mask itself often. So the difficulty of placing and removing of the filter is a problem.  The long sponge pads you put on both sides of the nose area to cushion the stiff wire do not really work, and they don't stay on when you wash. In fact, one came off as I was washing, and went in the drain.  Overall, it is not worth the price, and I cannot return it since I've worn it.
