Has anyone got experience of this fumes mask from 3m?
I can't find them here in the UK and bought my one off ebay and it came from the US.
I ask because I can still smell fumes through the mask even though it's tight on. I came across this mask on other welding forums and it is for welding and a trusted brand - 3M. After searching for a supplier in the UK I found it on ebay from a seller in the US. The forums where I heard about this mask coincidentally are US forums. Anyway, should you still smell fumes thorugh the mask or not? Maybe it doesn't work like a paint mask where you dont smell anything - maybe the filters stops particles but the smell still gets through. Given it's 3M I'm very surprised (disappointed) that it doesn't seem to be 100% effective. or it could be a fake - wouldn't be difficult to copy these things. Any comments welcome. Thanks.
