Hey when i load this addon, i get https://i.imgur.com/sOCzLc4.png this error.
In game i dont see any info about filtering inpact on polution. Does it still work as of 17.x?

Hey there,
yes, it is working as intended with 0.17.x. Those are deprecation warnings, which will soon be a problem of mine :D I will keep the mod updated to keep working as the devs make updates to the base game.
The machines actually filter pollution as follows:
MK1: 12/tick
MK2: 84/tick
MK3: 1500/tick

For example a mining drill produces 9 pollution (as stated in the entitiy information when hovering a built one). One MK1-Filtering Machine will be enough to completely remove the pollution created.
I hope this helps you for now. If you have further questions, go ahead :)

Greetings,
Schorty
