We already know that through photosynthesis, plants help us by taking carbon dioxide from the air and releasing pure oxygen into the atmosphere. Ever since NASA investigated the potential for plants to clean the air of super-sealed space stations in the 1980s, people have been inspired to improve their environments with houseplants. 

When it comes to removing toxins from the air, the bigger the plant and its leaves, the better its ability to purify the environment. How many plants do you need to achieve fresh, healthy air? The answer lies in many factors, such as the types of furniture and carpet used and their ages, whether smoking occurs on the premises, and how well the dwelling is sealed. Start with one or two handsome specimens, and see where your quest for a healthy atmosphere takes you when you grow these air-purifying plants.
