"Finally here's a respirator that doesn't mist up my glasses when I use it. It's expensive but at least I can see what I'm doing while avoiding breathing in sanding dust. It also helps with fumes but doesn't seeem to eliminate them. It's a bit fiddly to get on at first, but once you get the hang this is fine. If only it wasn't so expensive . . ."
"I have used many dust masks. I must say this mask was comfortable. The soft fabric fitted easily to my face I had none of those leaky bits on my cheeks bones that let dust in. The valve is a must and makes it easy to wear.
There was none of the characteristics of dust getting up my nose either.
So well done 3M.
Why didnt I score it full marks, well here has to be room to improve and I have only worn it for 4 hours."
