Pothos (Epipremnum aureum) is well-regarded for its ability to purify indoor air. Here’s a deeper look at how it helps with air purification:

Air Purification Mechanism
Absorption of Pollutants: Pothos plants absorb airborne toxins through their leaves and roots. The plant’s tissue can take in harmful substances like formaldehyde, benzene, and xylene, which are commonly found in indoor environments due to materials like carpeting, furniture, and cleaning products.
Bioremediation: Once absorbed, these toxins are broken down and converted into less harmful substances through metabolic processes within the plant. This helps in reducing the overall concentration of these pollutants in the indoor air.
Microbial Activity: Pothos plants support beneficial microorganisms in the soil, which can further help in breaking down organic pollutants and improving overall air quality.
Specific Pollutants Targeted
Formaldehyde: This chemical is found in many building materials and household products. Pothos has been shown to effectively reduce formaldehyde levels in indoor environments.
Benzene: Often present in air due to gasoline fumes and industrial emissions, benzene can be absorbed and removed by pothos.
Xylene: This solvent is found in some paints, varnishes, and adhesives. Pothos can help mitigate its presence in indoor air.
How Effective Is It?
NASA Clean Air Study: Pothos was highlighted in NASA’s Clean Air Study as one of the plants that could effectively purify indoor air. While the study demonstrated the potential for plants to improve air quality, real-world results can vary depending on factors like plant size, number of plants, and the concentration of pollutants.
Practical Benefits: For practical purposes, having a few pothos plants in a room can contribute to a reduction in indoor air pollutants and improve overall air quality. However, it’s important to note that while plants can help, they are not a substitute for proper ventilation and regular cleaning.
Care and Placement
Light: Pothos can thrive in low to bright, indirect light. While it prefers indirect light, it is adaptable and can tolerate various light conditions.
Watering: Keep the soil moist but not waterlogged. Pothos is relatively low-maintenance and can tolerate occasional neglect.
Temperature: Pothos prefers temperatures between 60-85°F (15-29°C). Avoid placing it in drafts or near heat sources.
In summary, while pothos is not a replacement for an air purifier or proper ventilation, it can be a beneficial addition to indoor spaces by helping to reduce airborne toxins and contribute to a healthier living environment.
