What Are the Best Air Purifying Indoor Plants for the Home?

Last Updated: August 20th, 2021

Do you know that the indoor air you breathe contains several toxins, dust particles, and germs? This air pollution is responsible for many airborne diseases and allergies. Have you heard about air purifying indoor plants? Do house plants really purify the air of your home? Or is it a myth? Let’s explain it with scientific evidence.

In 1989, NASA made a study stating that many air-purifying plants can reduce indoor air pollutants such as volatile organic solvents and other toxins. After this study, people started lining up their window sills with greenery. Recent research published in 2019 shows that NASA’s studies were based on experiments on plants in the sealed containers. In contrast, you can’t expect the same result from the plants indoors. You have to place 10-1000 plants per square meter of the building floor to achieve purified room air.

Indoor air purifying plants have a lot of benefits. They can clean some of the air you breathe, if not all of it. They give you a fresh feeling and help you cope with mental illnesses such as depression and anxiety. Moreover, they help reduce stress levels and improve mood swings. Let’s jump in to find the details of some of the best air-purifying plants for your home.
