Add machines that use craftable and refurbishable filters (and electricity) to clear pollution
empty word without any pollution... air filters are running....
air filter machines run 24/7 (as long as you put in filters) regardless of pollution, they never stop.
like whats the hole point of having to make filters??? and another point ... somehow the carbon dioxid gets consumed and need to be refilled? isnt it like you should get carbon out of the air additionaly?
