From my point of view: almost nothing to be honest. Okay, when I paint, I dont wear my best clothes and Im using acrylics in 90%. The other 10 are enamels for metal colors etc (but I found out that Vallejos brand new acrylic metals are very good too!).
One thing what is important nevertheless is a mask. Its from Moldex and helps a lot. Maybe I have to get some additional active coal filters too for the perfect result. The safety goggles shown below arent used that often - just because I wear my glasses under it as well.

I read that Mostrich uses Draeger masks, heard a lot of good things about them too..
Come to the dark side... we have cookies!
