The difference between the Origami Dripper S or M and the Origami Air S is the material. While the normal Origami Drippers are made of porcelain, the Origami Air S are made of AS resin. The Origami Air S are therefore slightly lighter and more robust than the porcelain drippers. In addition, thanks to the resin, the temperature can be kept constant during the brewing process. However, both materials are dishwasher safe and are therefore easy to clean.
