Pure Over
Pure Over's whole pitch is a plastic-free, paperless brew: the dripper, diffuser lid, stir stick, and carafe are borosilicate glass, and the base and coaster are ceramic. There is no plastic and no silicone in the brew mechanism, and no paper filter to buy - the glass filter cone plus the coffee bed do the filtering. It is one of the few genuinely fully plastic-free brewers.
How clear are their specs?
States borosilicate glass and ceramic construction with a built-in glass filter and no paper filter; replacement parts (e.g. the ceramic base) are sold by material.
