House plants have the ability to purify the air. Indeed, a study conducted by Nasa in 1989 concluded that some plants are better for purifying the air than others, removing harmful toxins such as formaldehyde, benzine and other toxins found in cleaning products, paints and flame-retardants commonly found in the modern home.
