Possible Duplicate:
Can indoor plants recycle the air we breathe?

I usually hear that plants should be placed in working areas to supplement the higher oxygen needs of working humans, or on the other hand, that should never be grown in bedrooms because they drain oxygen for their own respiration during night.

I somewhat doubt this is significant in comparison to natural variation in oxygen flow from the outside...
