Technivorm MoccamasterMoccamaster White Paper Filters, 100 Count (Pack of 1)

How do these compare to the bunn commercial 12 cup? sturdier/thicker? we sometimes have problems with bunn filters collapsing while brewing.

Are these filters compostable?

what is the micron size?

Is there any plastic in these filters? I know they are bonded without plastic or glue. But is there plastic in the filter itself?
