Dew Dripper

The Deodorizer is an early-game gas-cleaning building used to remove Polluted Oxygen from the air. It is especially useful around structures that generate dirty byproducts, such as Outhouses and Wash Basins, and it is also commonly used while exploring new parts of the asteroid to turn small pockets of Polluted Oxygen into breathable Oxygen for later pumping into a colony.

A Deodorizer catches Polluted Oxygen in a star-shaped area centered on itself, reaching up to 2 tiles away in all directions. It does not affect gas behind mechanical doors or solid tiles, though liquid tiles do not block its reach. In practice, this makes it easy to place a liquid barrier between a Deodorizer and a Polluted Oxygen source to create a clean separation between the two gases.

When operating, the Deodorizer converts 90% of the Polluted Oxygen into Oxygen and consumes Filtration Medium while producing more Clay than it uses. This makes it valuable not only for air cleanup, but also as a steady source of Clay for Ceramic production. Because it can slightly overpressure the surrounding area, it can function as a high-pressure filter when connected to a gas tank for oxygen storage.

A few practical uses stand out:

• Place Deodorizers near Polluted Oxygen sources to keep work areas breathable.
• Use them beside Polluted Water pools, since Polluted Water slowly off-gasses into Polluted Oxygen over time; a line of Deodorizers can convert that gas into Oxygen without generating heat.
• Use them during exploration to clean trapped Polluted Oxygen before pumping the resulting Oxygen into base infrastructure.
• Do not rely on them to remove germs from the air; they clean the gas, but germs remain until they slowly die off after the oxygen has been purified.

Although this process is slow and cannot replace a dedicated oxygen production chain, it is a reliable low-tech way to improve air quality, recover useful materials, and manage polluted areas in the early game.
