@piggo Says a person whose garbage bin is full of packaging from the supermarket. Man, those little filters are the most normal decomposable filter paper in a round shape. You could have come up with a better argument.
And yes, there's a metal mesh to that gadget if you don't want filters.
@piggo But yes, personally, I do not see that little piece of paper as so bad in relation to all those other things I am doing just to be: e.g, that packaging, owning a car, or using Internet for shitposting (electricity of data centers).
I hope you also see that in relation to all sorts of luxury non-essential stuff you and me are doing (e.g., 3d printing), these little filter papers are probably the least problematic item.
