Can Outdoor Plants Purify Air?

The idea of using plants to purify the air has been around for some time, but only in recent years have research studies begun to confirm the effectiveness of this practice. The results of these studies indicate that certain outdoor plants can indeed help to reduce air pollution and improve air quality.

The first study to demonstrate the effectiveness of outdoor plants in purifying the air was conducted by a team at the University of Florida in 2015. The researchers tested a variety of common outdoor plants, including boxwoods, hibiscus, and rhododendrons, and found that they were able to reduce levels of ozone and particulate matter in the air by up to 40%. The study also found that these plants were able to reduce levels of formaldehyde and other volatile organic compounds by up to 50%.

More recently, a team from the University of California Berkeley conducted another study on the effects of outdoor plants on air quality. This study looked at both indoor and outdoor spaces, with a particular focus on urban environments.

They found that certain species of trees and shrubs, such as Chinese hackberry trees, were able to reduce levels of nitrogen dioxide (NO2) by up to 40%. NO2 is a major component of smog, so this is an important finding for improving air quality in urban areas.

In addition to reducing levels of pollutants in the air, outdoor plants can also help improve overall air quality by increasing oxygen levels. This is due to photosynthesis, which is when plants use sunlight to convert carbon dioxide into oxygen. This process not only helps cleanse the surrounding atmosphere but also helps regulate temperatures in urban areas where heat buildup can be an issue.

Conclusion: Can Outdoor Plants Purify Air? The answer is yes! Studies have demonstrated that certain varieties of outdoor plants can effectively reduce pollutants such as ozone and particulate matter as well as volatile organic compounds like formaldehyde from the air. In addition, these plants can also help increase oxygen levels through photosynthesis which helps cleanse and regulate temperatures in urban areas.
