AeroPress
AeroPress built its name on the Original, whose brewing chamber and plunger are polypropylene - hot water sits in plastic for the whole brew. AeroPress is transparent about this (they publish the exact polymer) and stresses it is BPA- and phthalate-free, but it is still a plastic hot-water vessel.
More relevant for plastic-avoiders: AeroPress now sells the Premium (double-wall borosilicate glass chamber, anodized-aluminum plunger, stainless filter cap) and the Steel (all-304-stainless double-wall vacuum chamber). Both move the water path onto glass or steel and leave only an LFGB-grade silicone plunger seal - a genuine plastic-free option in the same brewing style.
How clear are their specs?
AeroPress publishes the exact material of each part on its site and support pages - polypropylene chamber/plunger on the Original, borosilicate glass on the Premium, 304 stainless on the Steel, and LFGB-grade silicone seals.
