Plants play a significant role in improving indoor air quality, particularly in the context of HVAC systems, by absorbing carbon dioxide and releasing oxygen through the process of photosynthesis. This exchange not only helps to enhance the air’s oxygen levels but is also crucial for reducing carbon dioxide concentrations, which can build up in enclosed spaces.

Additionally, many plants have the capability to trap various air pollutants, such as volatile organic compounds (VOCs), which are commonly found in indoor environments due to off-gassing from furniture, paints, and cleaning products. These absorbed pollutants are then either utilized by the plant or broken down into less harmful substances through physiological processes, contributing to a healthier indoor atmosphere.

While other options reference important aspects of plant functionality, they do not encompass the comprehensive role plants play in both carbon dioxide absorption and pollutant trapping, which is critical for enhancing indoor air quality in conjunction with HVAC systems.
