Yes, plants are known to purify the air in a room. An influential study conducted by NASA in 1989 confirmed that indoor plants have the ability to remove formaldehyde and other volatile organic compounds (VOCs) from the air. These VOCs are commonly found in household products, building materials, and furniture, and they can negatively affect indoor air quality.

One plant that is particularly effective in purifying the air is the snake plant, also known as Sansevieria. The snake plant is a hardy succulent that is known for its air-purifying properties. It absorbs toxins from the air through its leaves and releases pure oxygen. Unlike most other plants that release carbon dioxide during the night when there is no photosynthesis taking place, snake plants continue to produce oxygen.
This makes snake plants an excellent choice for indoor spaces, especially bedrooms, as they can help improve air quality and promote better sleep. In addition to formaldehyde, snake plants also have the ability to remove other harmful chemicals such as benzene, trichloroethylene, and xylene from the air.
Overall, the NASA study and other research have highlighted the beneficial effects of indoor plants, including snake plants, in purifying the air and promoting a healthier indoor environment. Incorporating plants into your home or office can help reduce the presence of harmful chemicals and improve air quality.
