NASA: These 18 Plants Will Produce The Cleanest Air In Your Home

With all the pollution out there, our homes are a sanctuary not only for our ears but also for our lungs. Clean air is sometimes hard to come by, especially in the cities. With all the time we spend even just sleeping at home, a healthy home environment becomes crucial to your health. After all, it’s an environment you control. So how do you keep the air as fresh as possible in your home? By taking a little bit of nature inside your home.

Trees and plants help absorb some of the most notorious chemicals from the air outdoors, so it’s no secret, that houseplants cold help us do the same indoors. NASA’s Dr. B.C. Wolverton led a study about 27 years ago and found 18 most effective plants for air-cleaning.

What’s Lurking in Your Home?

These 18 plants can be effective in removing trichloroethylene, xylene, ammonia, formaldehyde, and benzene. These chemicals have been linked to eye irritation, dizziness, headaches, and even more serious conditions like kidney damage and coma.  The health effects depend on the amount of the chemical you are exposed to, how you are exposed to it, its duration and the form that it exists in.

Here are some of the chemicals that lurk in and around your home and their symptoms:


Short-term exposure side effects:

Dizziness, nausea, headache, vomiting (followed by drowsiness or coma).


Short-term exposure side effects:

Irritation of nose, throat, and mouth. In severe cases swelling of larynx and lungs.


Short-term exposure side effects:

Drowsiness, eye irritation, dizziness, increased heart rate, headache, confusion, and unconsciousness in some cases.


Short-term exposure side effects:

Headache, confusion, throat and mouth irritation, dizziness, heart complications, liver/kidney damage and coma.


Short-term exposure side effects:

Coughing, sore throat, eye irritation.

The findings indicate that the Peace Lily and Florist’s Chrysanthemum are the most effective in doing their jobs. NASA recommends that you keep at least one plant per 100 square feet (10 square meters). While this study may look dated, it’s still one of the most accurate and comprehensive studies of its kind. Here’s an infographic from Love The Garden with the results.

Get The Plants For Your Home

Consider plants as natural air filters that will not only make a cleaner but will create a more beautiful environment for your home as well. They cost even less than a home filter and all you have to do is water them. Find them in your local flower/plant/grocery markets or order them online. Just make sure you do your research if you have any cats/dogs to see if they can be allergic to them if eaten.
