Indoor Plant Study Demonstrates Three Species Boosting Home Air Quality, According to ICARE Research
In the heart of India, the bustling city of Delhi-NCR is battling urban pollution. But a new research study, published on 02 May 2025, offers a sustainable and affordable solution to improve the air quality in our homes.
The Commission for Air Quality Management (CAQM) has directed immediate enforcement of pollution control measures across Delhi-NCR, following a decline in the city's air quality. This enforcement is part of a 27-point Action Plan under Stage I of GRAP (Graduated Response Action Plan).
The ICAR-Directorate of Floricultural Research has confirmed that specific indoor plants can mitigate indoor air pollution in India. Out of 30 ornamental plant species tested, three plants have shown exceptional abilities in purifying the air and enhancing oxygen levels. These plants are the Aglaonema commutatum (Chinese Evergreen), Dypsis lutescens (Areca Palm), and Codiaeum variegatum (Garden Croton).
The Aglaonema commutatum thrives in low-light conditions and filters airborne toxins like toluene and xylene. The Codiaeum variegatum aids in reducing carbon dioxide and potentially harmful VOCs (volatile organic compounds), while adding aesthetic value to our homes. The Dypsis lutescens is effective in removing indoor air toxins such as benzene, formaldehyde, and carbon monoxide, and acts as a natural humidifier.
According to the research, a single plant from any of these three species can purify the air in a room up to 250 cubic feet. To maximise the benefits, it is recommended to place at least one plant in each room.
This study is significant due to the increasing cases of respiratory ailments, allergies, and lifestyle-related diseases worsened by poor indoor air quality. The research is the first comprehensive study conducted in India under Indian climatic and environmental conditions, supporting earlier global studies like NASA's Clean Air Study.
Urban pollution finds a sustainable and affordable solution in the adoption of air-purifying plants for healthier living. Let's bring these plants into our homes and breathe easier.
