Dont worry, my husband has an air filter mask as he does a lot of turning and I have a mask too. Some of the foreign exotic woods you have to be very careful with. We turned some acrylic, and the smell, even with the masks on, was awful, you could taste it if you know what I mean and the workshop stank for days, so Bob went and turned some Camphor to get rid of the smell!! We wont be turning any more acrylic. We will stick to wood.
