28 best air-purifying plants for the home
Looking for air-purifying plants? Some scientists have suggested that choosing the right air purifying plants for your home can help detoxify the air in your living spaces, meaning your houseplants not only look lovely but work a little harder to clean the air you breathe in.
NASA's Clean Air Study found that there are a number of air purifying plants that can detoxify your home from the airborne toxins, dust and germs that can be found in a variety of household products, materials and furniture.
A follow-up study in 2019 showed that to make a substantial difference to the air quality inside your home, you would need a large number of house plants working together to clean the air – up to 93. It must be noted that plants should not be considered a substitute for an air-purifying device.
That said, plants can go some way to help detoxify the air, alongside other measures. The best air-purifying plants include the Peace Lily, Aloe Vera, Dracaena, Spider Plant, Boston Fern and Chrysanthemums.
Read on for our list of the best air-purifying plants and how to care for them so that they thrive…
