will it hold up in water straining small amounts of dirt? meaning will the fibers fall out of the mesh?

Have a look at fish tank filters, they do pretty much what you're looking for, and yes the fiberglass mats do eventually have to be replaced, but that's generally because they are clogged with dirt, rather than the filter media degrading.

Aren't charcoal filters biodegradable?

>>950177
I'm not sure but activated carbon filters are not. Otherwise their purpose would be non existent.

No because the already are degraded biological matter.
