===Life support===
{{see also|ISS ECLSS}}
''Mir''<nowiki>'</nowiki>s [[ISS ECLSS|environmental control and life support system]] (ECLSS) provided or controlled [[atmospheric pressure]], fire detection, oxygen levels, waste management and water supply. The highest priority for the ECLSS was the station's atmosphere, but the system also collected, processed, and stored waste and water produced and used by the crew—a process that recycles fluid from the sink, toilet, and condensation from the air. The [[Elektron (ISS)|''Elektron'']] system generated oxygen [[electrolysis|electrolytically]], venting hydrogen to space. Bottled oxygen and [[chemical oxygen generator|solid fuel oxygen generation]] (SFOG) canisters, a system known as [[Vika oxygen generator|''Vika'']], provided backup. Carbon dioxide was removed from the air by the ''[[ISS ECLSS#Vozdukh|Vozdukh]]'' system.<ref name="SSSM"/> Other byproducts of human metabolism, such as methane from the intestines and ammonia from sweat, were removed by [[Activated carbon|activated charcoal]] filters. Similar systems are presently used on the ISS.

The atmosphere on ''Mir'' was similar to [[Atmosphere of Earth|Earth's]].<ref>{{cite web|url=http://science.howstuffworks.com/space-station2.htm|title=How Space Stations Work|last=Craig Freudenrich|publisher=Howstuffworks|date=20 November 2000|access-date=23 November 2008|archive-date=12 December 2008|archive-url=https://web.archive.org/web/20081212014934/http://science.howstuffworks.com/space-station2.htm|url-status=live}}</ref> Normal air pressure on the station was 101.3&nbsp;[[kilopascal|kPa]] (14.7&nbsp;[[Pounds per square inch|psi]]); the same as at sea level on Earth.<ref name="SSSM"/> An Earth-like atmosphere offers benefits for crew comfort.<ref>{{Cite web |last1=Magazine |first1=Smithsonian |last2=Goss |first2=Heather |title=Why Living in Space Can be a Pain in the Head |url=https://www.smithsonianmag.com/air-space-magazine/why-living-space-can-be-pain-head-180951507/ |access-date=2024-10-16 |website=Smithsonian Magazine |language=en}}</ref>
