Our assessment
This is a manufacturer-document review, not a brewing or lab test. We have not used this brewer.
Its appeal is the parts list. The maker names a material for every part that water or coffee touches, from the glass reservoir to the steel showerhead and the silicone lid seal. That is more detail than most brands publish, but it is still the maker’s declaration. We found no independent teardown or particle test of the current model, and we found no published study that has measured what any home coffee maker sheds.
Silicone is a synthetic rubber, so this is a plastic-free brew path by the maker’s definition rather than a polymer-free one. Buy the model named Plastic-free: the shared manual also covers the brand’s Glass and Thermal models and mentions plastic parts that touch liquid.
If your current coffee maker works, keeping it is a reasonable choice. The cheaper routes, a steel percolator, a glass pour-over or a steel French press, give up automation or change the style of coffee.
