I got one of their FF400 face shield respirators to do lead paint removal and spent dozens of hours in unconditioned spaces with a tyvek suit. They are extremely well designed and never fog because the inhaled air passes first through the face mask area and then through one-way valves into the mouth/nose section and is exhausted downward at the front of the mouth/nose area.
- eropple 3y agoYeah - this is why it wasn't a good idea to use those during COVID, but it's amazing for doing work.
- rainbowzootsuit 3y agoI used it during the beginning of COVID to protect myself up until I was vaccinated and went for about 18 months before getting infected. Definitely got some odd looks at Costco. Maybe you are meaning for medical staff? Yeah there's a fully unfiltered exhaust stream blowing downwards.
- eropple 3y agoI mean that if you have COVID, the blow valve means you can readily expose other people. N95 masks are safer all around.
