Which plant removes most CO2?

When it comes to maximizing carbon dioxide absorption in indoor settings, plants with high rates of photosynthesis and large leaf surface areas—such as the Areca Palm, Snake Plant (Sansevieria), and Rubber Plant—are frequently cited as top performers. Notably, the Snake Plant and certain succulents utilize a specialized photosynthetic pathway known as Crassulacean Acid Metabolism, which allows them to capture carbon dioxide and release oxygen during the nighttime hours, making them uniquely adapted for indoor environments. However, it is important to note that even the most efficient indoor plant absorbs a relatively small amount of CO2 compared to the volume exhaled by human occupants, meaning plants should be viewed as a supplemental decorative touch rather than a primary ventilation solution.
