Great quality!
I am an honest-to-goodness purchaser and I really do not post many reviews.  Plus, I am skeptical of many reviews these days. That is why I really wanted to post a review for this mask. I really liked it.  It fits my face well and it came with filters. When the filters you get run out, you can use your own.  I will be ordering at least one more.  Caveat: I haven't run it through the washing machine so I don't know if they can be machine washed. I wash some of my other ones in hot water in the washer by putting them in a small lingerie bag.
