Isn't the rubber lid under the highest mechanical stress? What material did they choose there to avoid plastics?
Not a specialist, but I guess that friction would rub off microplastics both from the lid and the main part, and of the main part is metal, it eliminates that part at least.
And, the mystery plastic would some how get past the paper filter (micro cellulose!).
Aero presses don't wear out.
This thread is giving me microplastics.
