Snake plant is a native of tropical countries like India, Indonesia, and Africa. This plant has a typical evergreen sword-shaped leaves propagate mainly creeping rhizome. Due to the succulent nature of the snake plant, it requires less water to survive(1). The plant is grown both indoors and outdoors as a decorative plant.
Do Snake plants clean the air?
Yes, Snake plant cleans the air. This plant is not only known for its beautiful foliage structure but also as an efficient air purifier as per the NASA research report. The plant absorbs indoor air pollutants like benzene, formaldehyde, xylene, and toluene. Along with this the snake plant also has a higher efficiency of absorbing carbon dioxide (2) and it is one of the few plants that release oxygen during the night. This property of releasing oxygen during the night makes the snake plant a beautiful option as a bedroom plant.
1. Absorbs Carbon Dioxide
In a study done in 2015, it was observed that snake plants can remove carbon dioxide during night time and release oxygen. Thus helps in providing a better life quality and a healthy environment (2).
2. Absorbs benzene
According to WHO major sources of benzene are automobiles from the attached garage, heating and cooking systems, solvents. Exposure to benzene causes nausea, headache, and vomiting has a low but non-negligible carcinogenic risk. Source of benzene are tools and attached garages, gas and charcoal cooking, solvents, etc (3) (4). Snake plants help in the absorption of benzene in indoor conditions.
3. Removes formaldehyde
Snake plants help in absorbing formaldehyde from the air according to studies done by NASA. formaldehyde emits from cooking. Smoking, cosmetics, paints, etc. As per WHO studies indoor wooden furniture with formaldehyde resin paints are the main source of formaldehyde pollution (5)
4. Absorbs xylene
According to the Department of health and human service U.S.A., xylene is produced from a petroleum product. Typically indoor air has xylene 1-10 ppb. Buildings with poor ventilation have a higher indoor level of xylene. Other sources of xylene are paints and wooden furniture (6). Therefore snake plants are useful in the building with poor ventilation to absorb xylene from the indoor environment and thus helps in coping with sick building syndrome.
5. Absorbs toluene
Exposure to pollutant toluene causes central nervous system dysfunction and necrosis. Children exposed to these harmful pollutants also suffer developmental problems and reproductive problems in females. Irritation of upper respiratory tract and eyes. The major source of toluene pollution is gasoline, solvents in paints, plastic and soda bottles, paint cosmetics and other organic chemicals (7). Snake plants also help in removing toluene from the indoor environment.
