#3: Rubber Plants and "Janet Craigs."
Got a dim office that's just screaming out for cleaner air and a little touch of nature? Try a rubber plant or the dracaena "Janet Craig." Both will tolerate very little sun (though they may grow a little more slowly) and top the list for formaldehyde removers, which is particularly important in offices where most furniture is made from particleboard held together by formaldehyde-based glues. Janet Craigs will tolerate more abuse and neglect than rubber trees, but rubber trees are a little more aesthetically pleasing.
