health, you will share about my experience with welding helmets.
We Speedglas 9002V owner of Celan air filtration unit.
helmet is completely covered with cloth underneath, which is designed for this type, see the accompanying video.
this prevents the ingress of gases and irritating pollutants under space helmet. I dare say that it's really 90% protection from dust and harmful gases.
It follows the same filter unit Adflo.
there is no evaporating helmets, oxygen breathing filtered and are still forced to take off your helmet.
I attach here a video that says it all.
