Top 10 Air Purifying Plants
Air Purifying Plants
Cities with abnormal air pollution have always made the headlines. Burgeoning population, space crunch, multiplying petroleum driven vehicles, smoking, use of non-herbal paints, cleaners and penetration of plastic in our daily lives have made the situation unavoidable. Plants don many hats. They release oxygen and mop up the carbon dioxide. They emanate positive energies, and beautify the milieu.
However not many are aware that plants also purify the air naturally and filter toxins that are left suspended in the air due to chemicals, paints, and use of plastics. The National Aeronautics and Space Administration (NASA) Clean Air Study was conducted in association with the Associated Landscape Contractors of America (ALCA). The study showed that certain common indoor plants provide a natural way of removing toxic agents.
Peace Lily
Peace lily or Spathiphyllum is the most common house plant. Peace Lilies have white flowers that bloom in early summer and then continue to bloom the rest of the year. Its soil needs to be kept moist without overwatering. Peace lilies enjoy medium to low light. According to NASA's study, this plant removes the maximum number of toxins. It is however toxic to dogs and cats.
Pollutants purified - benzene, formaldehyde, trichloroethylene, xylene, toulene, ammonia.
Florist's Chrysanthemum
Florist's chrysanthemum or Chrysanthemum morifolium is a perennial plant that belongs to the Asteraceae family. Their vibrant colors splash liveliness and joy wherever it is grown. The "Festival of Happiness" in Japan celebrates the flower. They are also called 'mums' and they start to bloom in early autumn. According to NASA's study, this plant like Peace lily, removes the maximum number of toxins.
