Are you sure that the mod works correctly? There is information that the developers have removed all the tools that reduce pollution except from trees.

The same question. The value of pollution show XXX/0.0/-0.007 don't reduce even 0.001.

Oh, well. It works. It reduce the base pollution at the trunk.

ok so i have looked through the mod to try and find how pollution is being reduced (so i can make my own similar mod)

but there is nothing, this mod only adds machines, items and recipe's

it does nothing to clean the pollution out of the air.
can someone clarify if i have missed something?

The entities emissions are negative causing the pollution created by the machines when building the used air filters to be negative
