Weeping fig (Ficus benjamina)
A ficus in your living room can help filter out pollutants that typically accompany carpeting and furniture such as formaldehyde, benzene and trichloroethylene. Caring for a ficus can be tricky, but once you get the watering and light conditions right, they will last a long time.
The New York Botanical Garden says the weeping fig likes consistency and looks its best when grown in bright, indirect light. "It is challenged by dramatic temperature and light-level fluctuations."
