What has been suggested about the impact of indoor plants on IAQ?

Indoor plants have been the subject of research regarding their potential to improve indoor air quality (IAQ). It has been suggested that they may help enhance IAQ by absorbing pollutants, increasing humidity through transpiration, and providing psychological benefits that contribute to overall well-being.

While there is some evidence that certain plants can remove specific volatile organic compounds (VOCs) from the air, the extent of their effectiveness in purifying air on a significant scale is more debated. Numerous studies indicate that while plants can contribute positively to indoor environments, their benefits are often more nuanced and intertwined with other advantages, such as improving aesthetics and promoting mental health.

The other options do not capture the nuanced perspective that indoor plants, while potentially helpful for IAQ, are not solely responsible for major air purification but rather complement various aspects of indoor environments. This understanding highlights the multifaceted role of plants and emphasizes that their contribution goes beyond mere pollution control, making option B the most accurate representation of current research on the topic.
