17 Air-Purifying Plants That Can Help Eliminate Toxins Indoors

With their wide variety of colors, textures, and sizes, houseplants are an easy fix when you need to liven up your interiors, no matter the season. But in addition to serving an aesthetic purpose, many different types of greenery also double as air-purifying plants that help remove toxins from our environment, according to research by NASA.

NASA’s 1989 Clean Air Study explored natural ways to purify the air in small, unventilated spaces, like the International Space Station. While most of us will never leave our terrestrial home, the study’s findings are still important. The researchers report that certain indoor-grown plants could help alleviate the “sick building syndrome” associated with many newer buildings. According to the study, “Low-light-requiring houseplants…demonstrated the potential for improving indoor air quality by removing trace organic pollutants from the air in energy-efficient buildings.”

The plants included in the study were found to filter out toxic airborne pollutants including benzene, formaldehyde, and trichloroethylene. According to the World Health Organization, more than three million people die prematurely each year from diseases caused by household air pollution. Dr. Bill Wolverton, the study’s lead investigator and formerly a senior research scientist at NASA’s John C. Stennis Space Center said, “We feel that future results will provide an even stronger argument that common indoor landscaping plants can be a very effective part of a system used to provide pollution-free homes and workplaces.”

When choosing air-purifying plants to populate your own indoor jungle, Shaun Murphy from Indoor Sun Shoppe in Seattle recommends familiarizing yourself with the plants’ care requirements. While all of the plants on NASA’s list don’t require a lot of light, their water and soil needs vary. “All of these plants can be grown successfully when conditions are right,” says Murphy.
