What kind of mask, preferably with changeable filters, should I wear when working with plastic? Cutting, heating and glueing it. And 3d printing.
Something I can buy at a hardware store (or similar)
I'm getting overwhelmed with information when I try looking it up

@amro@todon.nl An organic vapor + particulate combo filter will give you pretty broad spectrum protection against both gaseous decomposition products (adsorbed onto activated charcoal) and aerosolized dust (trapped by particle filter). Something like the 3M 60921 cartridge. They will fit both half and full face masks from 3M. Personally I find full face more comfortable especially if you need eye protection anyway, and the design of the air path draws clean outside air over the lens and prevents fogging. Some people like half faces though. If you're not dealing with a fine dust or vapor that can irritate your eyes, either will work.
