Bedroom plants

Some people believe that plants will compete with you with oxygen and also releases carbon oxide with will harm you. This is a myth, not only the presence of plants in your bedroom isn't harmful it is actually beneficial, since it filters pollutants like benzene and formaldehyde from the air and possibly releases oils (I haven't found a source for this last claim).
Just for fun here is how much carbon dioxide a human releases. People are generally not afraid to sleep in a room with another human, so it is absurd to be wary of plants stealing your oxygen.
My middle school biology teacher believed this myth, I know this doesn't really belong on a wiki, but I found it funny.
