Like aloe, it produces oxygen and removes carbon dioxide from the air at night. Your slumber will definitely be more restful with Sansevieria Trifasciata in your bedroom. This plant requires almost no care. Light helps its growth, but it does fine in the darkness too.
Snake plants. "Forgetful gardeners: Snake plant (Sansevieria trifasciata) – this is found in woodland and forest margins in tropical west Africa and the Congo, so it tolerates low light and dry conditions. This one thrives upon neglect." Sounds like something even I might be able to keep alive!
