Materials used in the AeroPress coffee maker
All of the AeroPress parts except the rubber like seal are made of polypropylene. We made the change because tests indicated the polypropylene is more durable than copolyester. We regret the polypropylene is less transparent but feel the additional durability is more important. All materials used in the AeroPress are free of BPA and phthalates, are made in the USA, and are FDA and EU approved for use in contact with food.
Evolution of AeroPress
Versions 1 and 2
Oct 2005 – Jul 2009
Made of polycarbonate, a bluish-tinged material that contains BPA. When we learned about the health concerns associated with BPA, we had the polycarbonate tested. No BPA was leaching from the AeroPress into the brewed coffee.
Aug 2009 – Aug 2010
Switched to a crystal clear BPA free copolyester in August 2009 to assure customers of a BPA free material.
Sep 2010 – Dec 2013
Added a smoky grey tint.
Jan 2014 – Jun 2014
Switched the color of the numbers from blue to gold and added the word “AeroPress”. Made it easier for consumers to tell a real AeroPress from a counterfeit.
Versions 6 and 7
Jul 2014 – Present
Switched materials to polypropylene and switched to beige lettering on the chamber (Version 6). Then switched to a gold foil lettering that adhered better to the polypropylene and decreased the amount of grey tint (Version 7).
What material do you use for the seal?
It is a medical grade thermoplastic elastomer that we buy from a supplier for medical syringes. The chemical name is styrene-ethylene-butadiene-styrene. It is made in the USA and is FDA and EU approved for use in contact with food.
Does the AeroPress contain BPA or phthalates?
No. The AeroPress has always been free of phthalates and has been free of BPA since August of 2009.
