Plants are indispensable to human life. Through photosynthesis, they convert the carbon dioxide we exhale into fresh oxygen, and they can also remove toxins from the air we breathe.
One famous NASA experiment, published in 1989, found that indoor plants can scrub the air of cancer-causing volatile organic compounds like formaldehyde and benzene. (Those NASA researchers were looking for ways to effectively detoxify the air of space station environments.) Later research has found that soil microorganisms in potted plants also play a part in cleaning indoor air.
Based on this research, some scientists say house plants are effective natural air purifiers. And the bigger and leafier the plant, the better. “The amount of leaf surface area influences the rate of air purification,” says Bill Wolverton, a former NASA research scientist who conducted that 1989 plant study.
How plants can purify the air?
Indoor plants remove pollutants from the air by absorbing these gases through their leaves and roots. The microorganisms that live in the soil of potted plants also play an instrumental role in neutralizing VOCs and other pollutants.
While most leafy plants are adept at purifying indoor air, some of the plants that scientists have found most useful in removing VOCs include Japanese royal ferns, spider plants, Boston ferns, purple waffle plants, English ivy, areca palms, golden pothos, aloe vera, snake plants and peace lilies.
Can Indoor Plants Really Purify the Air?
On one hand, it absorbs the carbon dioxide in the air and vomit oxygen, effectively reduce the carbon dioxide in air and making air more fresh.
On the other hand, plants, especially forest or tropical plants, blocking, and absorbing the ashes in the air, refreshing the air.
In order to maintain life, human being have to take in oxygen and expire carbon dioxide.If the carbon dioxide in the air is too high, people would hardly breath and be toxicated. Plants are the only creature in the world to photosynthesis, besides, it is the absorber of carbon dioxide and producer of oxygen.
There are other plants which can take in toxic gas like sulfur dioxide and carbon monoxide. Besides, some plants could even take in some harmful radiation to human body, such as the cactus put in front of the computer could take in large amount of radiation sent out by the screen.
