Do Plants Really Clean Indoor Air?

Plants have countless science-backed benefits in our daily lives aside from making our homes look vibrant and refreshing. I hate to break it to you but purifying indoor air is not one of them. You have probably heard of its benefits before or read a blog about it in the past. We all know that plants absorb carbon dioxide and release oxygen. However, contrary to popular belief, plants don’t actually clean or purify the air. It is a common misconception that makes you hope it’s true.

Do Plants Really Clean Indoor Air? Here’s what scientists say:

It all started with a famous NASA experiment published in 1989 which states that indoor plants can purify the air and remove cancer-causing VOCs or volatile organic compounds. NASA researchers are at that time are looking for ways to detoxify the air inside the space station. Former NASA research scientist Bill Wolverton who led the plant study in 1989 has written a lot of books on the topic.

But then, new research was published recently in the Journal of Exposure Science and Environmental Epidemiology which debunked the whole myth. The researchers of this study conducted an experiment by putting a plant in a tiny container and exposing it to VOCs or volatile organic chemicals. They later found out that an indoor ivy plant can remove two-thirds of the toxic chemicals they were exposed to.

The problem is that our homes are not like one of those gaseous chambers in which the plants are placed during the experiments. It’s not easy to gauge how plants actually react to chemicals in the air when they are out in the open. While plants do help in removing toxins, they do it much slower compared to mechanical air purifiers.

It would take roughly ten plants per square foot to lower VOCs sufficiently to have an influence on air quality. That’s 5,000 plants in a 500-square-foot flat, a true jungle.

While some findings are still subject to research, this claim does not necessarily mean indoor plants are useless. They do provide certain benefits to your health that can improve your overall wellbeing.

7 Great Benefits of Houseplants

This is most likely because we all want to have a break from the stress and anxiety that’s brought about by the pandemic.

Keep in mind though that before you decide to have indoor plants at home, make sure to do your research about toxic plants that may be harmful most especially if you have kids or pets at home.
