There are several ways to clean polluted oxygen in Oxygen Not Included. One way is to use Air Deodorizers and Pufts to remove polluted oxygen. Another way is to create a slime-to-algae machine, pump the polluted water into a fertilizer maker, and then create a natural gas generator near it to absorb the natural gas. A CO2 scrubber can then be used to get rid of the carbon dioxide, and the wastewater can be pumped back into the fertilizer maker. Additionally, it is important to identify the source of the polluted oxygen and address any airflow issues in your base layout.

What You'll Learn
Use Air Deodorizers and Pufts to remove polluted oxygen
Polluted oxygen can be harmful to your colony in Oxygen Not Included. Breathing too much polluted oxygen causes the Yucky Lungs debuff, which increases the air consumption rate and causes coughing. It also causes food decay at twice the default speed.
To remove polluted oxygen, you can use Air Deodorizers and Pufts. Deodorizers are buildings that purify polluted oxygen in their vicinity, reducing the threat of Slimelung infection. They require 5 Watts of power and periodic supplies of filtration medium (such as sand) to operate. Deodorizers can collect polluted oxygen from two tiles away, and liquids do not block this reach. This allows for the creation of a perfect seal between oxygen and polluted oxygen by placing a liquid tile between the deodorizer and the polluted oxygen. Deodorizers convert 90% of polluted oxygen to oxygen and produce clay, which is useful for ceramic production. They are especially useful for cleaning the air near structures that emit polluted oxygen, such as outhouses and wash basins.
Pufts and Puft Princes are creatures that can breathe polluted oxygen and excrete slime. They can survive on the polluted oxygen emitted by geysers. While deodorizers are a more passive solution, some players consider Pufts to be the "only real way" to remove polluted oxygen.

Create a slime-to-algae machine and pump polluted water into a fertiliser maker
Slime can be converted into algae and polluted water using an Algae Distiller. This machine is heat-multiplying, with a higher output temperature than its input. The Algae Distiller will output polluted water through its output pipe and drop the created algae on the ground from its bottom right tile once 30kg has accumulated. As the Algae Distiller emits polluted water, heats up quickly, and has a low decor value, it should be placed away from living quarters or in a sealed room.
The polluted water can then be pumped into a fertiliser maker. This is a useful step as fertiliser changes into dirt when heated, and using polluted water and phospherite (both of which are infinite resources) means you can make a net amount of dirt. However, this process is not 100% efficient, with a 25% efficiency rate.
To prevent the creation of more polluted oxygen, a natural gas generator should be created near the fertiliser maker to absorb the natural gas. Then, a CO2 scrubber should be placed near the natural gas generator to get rid of the CO2. The CO2 wastewater can be pumped back into the fertiliser maker, and the CO2 scrubber can be connected to a pump machine near a steam geyser to keep the circle going. However, the natural gas generator will drip polluted water, so a pump should be placed underneath to collect this and pump it back into the fertiliser maker to prevent more polluted oxygen from being created.

Use a natural gas generator to absorb the natural gas
One way to clean polluted oxygen in Oxygen Not Included is to use a natural gas generator to absorb the natural gas. Here's a step-by-step guide on how to do it:
Firstly, create a slime-to-algae machine and pump the polluted water into a fertilizer maker. This process will produce natural gas, which you can then use as fuel for the natural gas generator. Place the natural gas generator near the fertilizer maker to absorb the natural gas it produces.
Natural gas generators produce electricity by burning natural gas and releasing carbon dioxide and polluted water as byproducts. The polluted water drips from the third tile on the left or the second tile on the right of the generator. By placing the generator above a waste reservoir or a large room with mesh tiles, you can collect the polluted water. This water can be reused for cooling high-temperature areas or even converted into steam and retrieved as clean water.
To continue the process, place a CO2 scrubber near the natural gas generator to capture and remove the carbon dioxide. Connect the CO2 scrubber to a pump machine near a steam geyser to maintain a continuous cycle. Ensure that the natural gas entering the generator is pure, as any impurities can damage the generator.
It is also important to manage the heat generated by the natural gas generator. At 150°C, the generator produces a significant amount of heat energy, which can be fed directly to a steam turbine to produce additional power. Stacking multiple generators vertically and connecting them to smart batteries can optimize energy production and prevent them from running at maximum capacity constantly.
By following these steps, you can effectively use a natural gas generator to absorb natural gas, clean polluted oxygen, and generate power in Oxygen Not Included.

Place an air pump with a filter set to natural gas in the problem area
To clean polluted oxygen in Oxygen Not Included, one method is to place an air pump with a filter set to natural gas in the problem area. This can be done by following these steps:
Firstly, identify the problem area where the polluted oxygen is located. This could be a specific room or area within your base. Once you've identified the problem area, you can proceed to the next step.
Next, construct an air pump and place it in the problem area. The air pump will be responsible for sucking up the polluted oxygen and other gases from the surrounding environment. Ensure that the air pump is properly powered and functional before proceeding.
Now, it's time to set up the filter on the air pump. The filter will determine which gases are removed from the air and which are allowed to pass through. In this case, you want to set the filter to target natural gas. This can be done by adjusting the settings on the air pump interface. The natural gas output will be indicated by an orange symbol, while the standard output for other gases is green.
After setting up the filter, you need to decide what to do with the separated natural gas. One option is to isolate it and send it to a specific area or generator, while another option is to create a natural gas generator near the fertilizer maker to absorb the natural gas. This natural gas generator will also produce polluted water, so be sure to place a pump underneath to collect it and send it back into the fertilizer maker to prevent further pollution.
Finally, you can vent the remaining gases, including clean oxygen, back into the problem area or wherever else you need them. This will help improve the air quality and provide breathable oxygen for your Dupes.
By following these steps and placing an air pump with a filter set to natural gas in the problem area, you can effectively clean polluted oxygen in Oxygen Not Included. This method, along with the use of Pufts, provides a way to manage air quality and maintain a functional and healthy environment for your colony.

Vent the polluted oxygen into space
Polluted oxygen is a dirty, unfiltered air resource in Oxygen Not Included. It is breathable and works similarly to oxygen, allowing duplicants to survive. However, it can spread Slimelung and Food Poisoning germs, and breathing too much of it causes the Yucky Lungs debuff, increasing the air consumption rate and causing coughing. It also causes food nearby to rot at a faster rate.
One way to deal with polluted oxygen is to vent it into space. There are two types of geysers that produce polluted oxygen: Hot and Infectious Polluted Oxygen Vents. Both yield around 95 g/s and are stifled at 5 kg of air pressure, with the latter spreading Slimelung germs. Polluted oxygen vents can be used for making clay and powering steam turbines, but they are not a very efficient source of power.
To vent polluted oxygen into space, you can use an air pump with a filter set to natural gas. The natural gas can be isolated or sent to a generator, while the rest of the gases are vented back into space. This method helps to remove the polluted oxygen from your base and prevent the negative effects it can have on your duplicants and food supplies.
Another way to deal with polluted oxygen is to use Pufts, which eat polluted oxygen and poop slime. This can be used to create a sustainable farm for infinite mushrooms. Additionally, you can create a slime-to-algae machine and pump the polluted water into a fertilizer maker. This helps to prevent the creation of more polluted oxygen.
