The suction of pollution is implemented per chunk, rather than per machine and updates are spread evenly over an interval of 20 ticks (default). The interval can be changed in the settings. - The [evolution](https://wiki.factorio.com/Enemies#Evolution) factor of enemies is based on the total amount of produced pollution. Cleaning it back up does not reverse this effect. This means that biters will still get stronger, no matter how proficient you are at cleaning pollution. You can prevent attacks caused by pollution reaching the biter nests however. - Pollution from other chunks is sucked toward air filters at an exponentially decreasing rate depending on the distance. The formula is `suction = base_suction * (1/4)^distance`. This means that filters only pull in approximately as much pollution as they can filter. - When an air filter machine or any other entity containing pollution is destroyed or mined, the pollution inside is dispersed back into the atmosphere.
