12 Air Purifying Plants You Must Have at Home (research by NASA)

Air Purifying Plants for Home

Are you looking to naturally reduce toxins in air inside your home? Air purifiers can do wonders to cleanup some of these, but there is another natural way to do this. Many air cleaning indoor plants can help you remove toxins and improve air quality inside home.

In a study by NASA, the leaves, roots, soil, and associated microorganisms of plants have been evaluated as a possible means of reducing indoor air pollutants.

The more plants, the better. To reap the benefits, have at least two plants per 100 square feet. Bill Wolverton, the man behind the NASA study, recommends palm, fern and ivy plants because they take up the most surface area.

How do plants purify air at home?

Let’s take it back to science class: During photosynthesis (you remember that word, don’t ya?), plants convert the carbon dioxide we exhale into fresh oxygen and remove toxins from the air we breathe. NASA tested this theory in a landmark 1989 study when they examined how popular houseplants diffuse toxic chemicals including:

  • Formaldehyde, which can cause irritation to nose, mouth, and throat.
  • Benzane, which can cause irritation to eyes, drowsiness, dizziness, increase in heart rate, headaches, and confusion.
  • Trichlorothylene, which can cause dizziness, headache, nausea, and vomiting.

In the study, they found several, no-fuss plants that actually filter out the bad stuff and easily grow indoors.

For home as well as car air purifiers, we periodically need to replace air filters and need extra maintenance. But these plants don’t have much headache and not even cost much to your pocket.

Rubber plants also eliminate bacteria and mold spores in the air.
