Weeping Fig Tree - Weeping fig is one of the best plants for improving air quality indoors. It has one of the top removal rates of toxins like formaldehyde, benzene and trichloroethylene from tainted indoor air.
Plants if you often forget to water: Hardy houseplants like ZZ (Zamioculcas zamiifolia, the tallest plant in our photo) tolerate neglect. Even with low light and infrequent watering, expect it to grow 3 feet tall and showcase glossy green leaves. More picks: dracaena and cast-iron plant.
