Can Houseplants Improve Air Quality?

The video discusses the potential of plants to purify indoor air, referencing a 1989 NASA study that showed plants could remove pollutants like benzene and formaldehyde in controlled lab conditions. However, later studies indicate that these results may not translate to real-world environments due to differences in conditions such as light and air circulation. Critics suggest that a large number of plants would be needed to achieve similar effects in a typical home. While some studies show plants can improve air quality, there is no consensus, and plants alone are unlikely to solve indoor air pollution issues.
