I'm only using the krastorio 2 mod. Should I expect the pollution to be pulled from nearby chunks?
I don't see it. How can i track it?

If chunk has lots of pollution already then it doesn't pull pollution. To track whenever it actually pulls pollution check energy grid stats, there should be suction interface

I put air filters in one chunk so that it turned out -1800 pollution per chunk. Neighbors remain a little dirty, as without these filters.
The consumption of these filters is 77.5 kW - their maximum consumption.
There are no other sources of consumption.
I created a separate electrical circuit with only filters and solar panels.
I use only Krastorio 2 mod.
