The ultimate low toxin coffee brewing vessel is a borosilicate pressure siphon.

Kazumi Siphon Coffee makes the leading vessel AFAICT. It's a delicate piece of engineering, beautiful, and requires a lot of tender care.

Using a pressure siphon eliminates the need to heat water up in a kettle, which reduces toxic load as much as you can.

All glass everything. No filter.
