Do Plants Help Indoor Air Quality

February 19, 2020

In 1989, the National Aeronautics and Space Administration (NASA) published a study claiming that plants have a positive impact on increasing indoor air quality. The researchers brought in common, popular houseplants, such as snake plants and peace lilies, to see if they can act as natural purifiers. The researchers found that the presence of these plants reduced volatile organic compounds (VOCs), like benzene or formaldehyde, which are certain types of air pollutants. The Story Is More Complicated The real story, however, is much less certain. While certainly, plants may help, the researchers conducted these experiments in controlled, plexiglass chambers the size of boxes. Our homes are far from these regulated chambers. In reality, good ventilation systems, which exchange indoor and outdoor air continuously, accounts for VOC removal in practice. It turns out, that while plants can improve indoor air quality, they are no substitute for quality air conditioning and ventilation systems because they simply filter too slowly. We at can install your air quality systems in Cleveland and across Northeast Ohio. Plants Help, but They Cannot Substitute Quality Air Conditioning So, do plants help improve air quality? In theory, they do. However, in real-life, their effects are very limited. An...
