It helped me a lot while wearing it, I could breathe comfortably, I could see!

But when they saw me wearing it in the Hospital, they said that these masks have been discontinued!

So I didn't wear it again, and went back to suffocating with the old original fabric washable one!

With this price, I will only compare it to disposable masks, even though it is not.
Yes, it is cheaply made and if you don't handle it carefully, it breaks easily.
But it is so convenient to have several.

Not a good application. The plastic is small and very thin and can easily break. You get what you pay for...
