Houseplants are plants that are grown indoors in places such as residences and offices, namely for decorative purposes, but studies have shown that they have positive psychological effects and as well as help with indoor air purification, since some species, and the soil-dwelling microbes associated with them, reduce indoor air pollution by absorbing volatile organic compounds. While generally toxic to humans, the pollutants are absorbed by the plant and its soil-dwelling microbes without harm.
