Improve Your Home's Air Quality With These Houseplants

Bringing houseplants into your home not only adds character and a bit of nature to the space, but they are quite literally a breath of fresh air. As it happens, your favorite houseplants are doing their part to keep your home a beautiful and healthy space. What could be better than adding personality and charm to your home while also improving air quality? It’s a win-win. 

Erin Marino, editorial lead and plant expert at The Sill, walked us through the ways in which houseplants can improve indoor air quality.

“Through photosynthesis, plants absorb carbon dioxide and release oxygen,” she explained. “Through transpiration, plants increase humidity.”

She also noted that there has been a lot of conversation around houseplants removing volatile organic compounds from indoor air. 

“Indoor plants are not the final answer to better air quality, but they can absolutely be a part of the solution,” Marino said. 

“They have the ability to exchange water and gases with their surroundings,” she explained. “Plants capture these indoor pollutants and convert them into stored energy, releasing naturally filtered air as a byproduct. They do this by absorbing the pollutants through their leaves and transmitting the toxins to their roots where they’re converted into a food source.”

Marino said some people hypothesize that bigger, leafier plants are better for improving the quality of indoor air. However, she noted that not much research has been done to compare different plant species in this way. 

“Most studies, including NASA’s famous 1989 experiment, were conducted in sealed, controlled environments, making it difficult to translate to our everyday conditions,” she said.

Still, you can absolutely benefit from bringing plants inside.

“Other studies have shown that indoor plants can boost your mood, reduce your stress, and even make you a more productive employee,” Marino said. “Even brief exposure to nature can elicit an unconscious calming effect.”
