The brand that makes Aeropress has replaced the material that is usually used to manufacture manual coffee makers. It now uses polypropylene which is regarded as the most robust plastic available. Except for the plunger's seal, each component of it is made of solid polypropylene plastic. Yes, Aeropress has been BPA-free since 2009. They first built it with co polyester (also BPA-free) and later permanently changed it to polypropylene.
