Many people grow flowers not to purify indoor air, but to make their homes look more natural and warm. From a scientific point of view, the ornamental value of plants indoors is the most important, and their ability to purify the air can be ignored.
When plants perform photosynthesis, they exchange gases with the outside world through the opening and closing of stomata. When plants inhale carbon dioxide, they can also absorb harmful gases in the air and release oxygen at the same time. Structures such as villi on the surface of plants can absorb dust floating in the air. In addition, plants can release water vapor to regulate temperature and humidity to a certain extent. Therefore, forests have always been called "lungs of the earth" and "natural purifiers".
