Living plants add natural beauty to our homes and workplaces, but did you know houseplants are also a valuable weapon against indoor air pollution? They can absorb harmful chemicals and improve air quality, making your home or office a more pleasant place to live or work The most common harmful airborne chemicals found in the average home or office are formaldehyde, benzene, trichloroethylene, and carbon monoxide. Even in low concentrations, these chemicals can cause a variety of health problems.Researchers have identified several varieties of houseplants that excel in removing these chemical pollutants from the air. The most effective in removing formaldehyde were the philodendron, spider plant, and golden pothos. The peace lily and the chrysanthemum removed the highest percentage of trichoroethylene. Since all plants utilize carbon in the process of producing new growth, all these varieties are effective in removing low levels of carbon monoxide. Other varieties found to be especially effective in cleaning the air were English ivy, Chinese evergreen, bamboo palm, snake plant (mother-in-law’s tongue), and several types of dracaena, including marginata, corn plant, and Janet Craig. All plants produce oxygen through the process of photosynthesis. Any plants you choose, in addition to the varieties named here, will increase the concentration of oxygen in their immediate surroundings. To beautify your surroundings, and breathe a little easier, add several of these living air cleaners to your home and work spaces. You will feel better and make your indoor environments more pleasant for living and working.
