The myth that keeping plants in the bedroom depletes oxygen has persisted, but research shows humans consume significantly more oxygen than plants, making it harmless.
NASA's 1989 study helped popularize the idea that certain plants can purify air by removing VOCs, but it was conducted in controlled, confined environments.
A recent study from 2019 re-evaluated NASA's findings, noting that the conditions of the initial experiment greatly influenced the results regarding plants' air purification abilities.
While some plants like gerbera, peace lily, and bamboo palm showed effective VOC filtration in NASA's study, they may not perform as well in typical indoor conditions.
