But that's also a difficult question right, is there really an insignificant number of nano/microplastics in filtered air of filtered water? From what I've heard in cloud development, small particles can float along with water vapor, no clue how this would work in Destillation for instant.

I'm no expert on microplastics, but i do work in science so i do see papers getting around how plastics keep popping up in unexpected places. Sure a DM2 lab is expected to be super clean and safe and all, but idk. Maybe im also just a bit scared-biased
