This is the dust and impact protection that I use in conjunction with a dust collector and micron air filter in the shop. A regular dust mask doesn't get the fine stuff and if something comes off the lathe (and it will happen) you don't get your teeth knocked out. I used to use a plain face shield and ended up with stitches in my eyebrow from being cut by the head band when a small piece came off the lathe and hit me. It only takes once.
