Peace Lily

Apart from being soothing to the eyes, the Peace Lilly also helps in air purification of the surroundings. It topped NASA’s list for removing all three of most common Volatile Organic Compounds — formaldehyde, benzene and trichloroethylene. To maximize the plant's air-cleansing potential, keep the leaves dust-free. All it needs is some shade and weekly watering to survive and produce blooms.
