ICAR-Directorate of Floricultural Research has confirmed for the first time in India that specific indoor plants can significantly mitigate indoor air pollution. This marks a crucial step forward in tackling the growing concerns over air quality within Indian households, offices, and urban spaces.
According to the research findings, out of 30 ornamental plant species tested, three indoor plants emerged as highly effective in absorbing carbon dioxide and enhancing oxygen levels. These are Dypsis lutescens (commonly known as Areca Palm), Aglaonema commutatum (Chinese Evergreen), and Codiaeum variegatum (Garden Croton).
The study revealed that even a single plant from any of these three species can purify the air in a room measuring up to 250 cubic feet. The plants showed a strong ability to not only reduce carbon dioxide levels but also contribute to better oxygen circulation indoors.
This research is particularly significant in light of increasing cases of respiratory ailments, allergies, and lifestyle-related diseases that are worsened by poor indoor air quality.
Air-Purifying Indoor Plants Identified by ICAR
-
Dypsis lutescens (Areca Palm): Known for its lush, feathery fronds, this plant is highly efficient in removing indoor air toxins such as benzene, formaldehyde, and carbon monoxide. It also acts as a natural humidifier.
-
Aglaonema commutatum (Chinese Evergreen): Favoured for its attractive foliage and low maintenance, this plant thrives in low-light conditions and filters airborne toxins like toluene and xylene.
-
Codiaeum variegatum (Garden Croton): With its vibrant, multi-coloured leaves, the croton not only adds aesthetic value but also aids in reducing carbon dioxide and potentially harmful VOCs (volatile organic compounds).
The ICAR’s findings support earlier global studies, including NASA’s Clean Air Study, which recognized the air-purifying potential of indoor plants. However, this is the first time such a comprehensive study has been conducted in India under Indian climatic and environmental conditions.
With urban pollution becoming a pressing issue, the adoption of air-purifying plants offers a sustainable and affordable solution for healthier living. Placing at least one plant in each room will maximize benefits.
