Plants are one of the most obvious good things that there can be, and certain plants are excellent at cleaning specific chemicals out of the air. We all know that plants clean the air, but what aspects of air they clean can change from plant to plant. Researchers tried to find which plants are best at cleaning gasoline vapour out of indoor air. Gasoline contains four chemical compounds which are also found in products that use volatile organic compounds (like fire retardent on a couch); so by studying which plants work best they can create an efficient plant based purifier.

The researchers and Ambius designed a Small Live Green Wall (SLGW) using indoor plants known for their phytoremediation abilities. Phytoremediation is the proper term for using plants to clean up contaminated soil, air and water is phytoremediation.

They tested nine SLGW systems, each containing devil’s ivy (Epipremnum aureum), arrowhead vine (Syngonium podophyllum), and spider plant (Chlorophytum comosum). A control was prepared that contained only potting mixture and no plants. The SLGWs were placed in sealed perspex chambers, exposed to volatile organic compounds, and then analyzed using gas chromatography-mass spectrometry.

If you’re looking for a simple list of what plants you can put inside today to start cleaning your indoor air then here you go:

1. Snake Plant (Sansevieria trifasciata): Snake plants are excellent at removing formaldehyde, benzene, xylene, and toluene from the air. They are known for their ability to thrive in low light conditions and require minimal maintenance.

2. Peace Lily (Spathiphyllum spp.): Peace lilies are known for their beautiful white flowers and their ability to remove common indoor air pollutants like formaldehyde, benzene, and trichloroethylene. They prefer shady areas and moderate watering.

3. Golden Pothos (Epipremnum aureum): Golden Pothos, also known as Devil’s Ivy, is a popular choice for indoor spaces. It is effective at removing formaldehyde, benzene, xylene, and carbon monoxide. It is an easy-to-care-for plant that can tolerate low light conditions.

4. Boston Fern (Nephrolepis exaltata): Boston ferns are known for their high transpiration rates, which helps to humidify the air and remove formaldehyde, xylene, and toluene. They thrive in bright, indirect light and require consistent watering.

5. Areca Palm (Dypsis lutescens): Areca palms are effective at removing formaldehyde, xylene, and toluene from the air. They are also known for their ability to add moisture to the environment. Areca palms prefer bright, indirect light and regular watering.

6. Aloe Vera (Aloe barbadensis): Aloe vera plants not only have medicinal properties but also help in purifying the air by removing formaldehyde and benzene. They prefer bright, indirect light and minimal watering.

7. Dracaena (Dracaena spp.): Dracaena plants come in various species like Dracaena marginata, Dracaena reflexa, and Dracaena fragrans. They can effectively remove formaldehyde, benzene, trichloroethylene, and xylene. Dracaenas thrive in moderate to bright indirect light conditions
