 This mod features three tiers of air filtering machines. These machines remove pollution from the air in their region by using air filters. Each consecutive tier has a larger radius and stronger filtering effect. Keep in mind that you will still need filters spread around your base at strategic locations to effectively counteract the spread of pollution.

 #### Air filter machine 2
 The upgraded version has a stronger filtering effect. In addition, by using a moderate amount of electricity this machine is able to pull in pollution from neighboring chunks in the shape of a diamond. This version has a radius of two chunks (in [manhattan distance](https://en.wikipedia.org/wiki/Taxicab_geometry)). Note that a continuous amount of energy is consumed for this suction effect in addition to the cost of filtering the air.
