The product in question is completely useless!! (I'm not exaggerating). Very poor quality of materials and construction.
When I received it, a piece of the mask was broken and the respirator is different. So, I contacted the store and they informed me that it will be replaced.
I didn't bother to send it back due to its low cost, but even more so because I would be away for a long period of time.
Although a piece of the mask was broken, it seemed that it didn't affect its use. So, I used it and in my attempt to wear it, it fell apart in my hands. Literally, the whole thing disassembled after the clips that hold the strap broke.
This experience was a lesson for me, you get what you pay for!!!
