09. Are there filtration systems on board? How often are they cleaned? Who is in charge of maintaining a clean internal environment? (A K2S Question)

From The Space Library

Activated charcoal filters are utilized in filtering out harmful gases produced by the astronauts, such as methane, carbon dioxide, and ammonia. High efficiency particulate air filters (HEPA) are also used to remove hair and dead skin produced by the astronauts (yes, we all shed skin continuously). The filters are changed out as required by the flight crew to maintain a clean environment.
