The Ozone Maker is an Eco building / airship used to reduce the pollution level and improve the Ecobalance of an island. Due to its tiny influence radius this is an extremely powerful ecobalance building.

However, if one wanted to raise the eco-balance by 300 for example, ark-upgraded Weather Control Stations are actually better. Twenty of said buildings will do the job for around 120 credits, where as three Ozone Maker Stations will cost 360 credits to maintain. Ozone Makers notably cannot be upgraded in order to reduce cost. However, this does not consider the space that Weather Control Stations take up (although it is reduced of course due to the upgrades), River Sewage Treatment Plants or Guardians (and upgrades for those), and the amount of ark storage space taken up by said upgrades.

The airship is also seen in the end of Chapter 2, Mission 3 as part of the Eden Initiative battle fleet.

Leon Moreau has a similar building called the Ozone Generator Station. It raises the ecobalance by +125, unlike the Ozone Maker Station, which generates +100.

  • The Ozone Maker flies at a fairly low altitude. Thus, if it really did what its name suggests and produced Ozone gas, then it would in fact be damaging the environment. Ozone is only beneficial in the upper atmosphere. The animation makes it look like it is scrubbing pollutants from the air so it might just be passively increasing Ozone in the upper atmosphere.
