8 Indoor Plants That Help Kill Viruses And Bacteria

Indoor Plants That Help Kill Viruses And Bacteria

Good news, these plants can help purify the air in your home!

Raise your hand if you’ve a) casually referred to yourself as a plantita; b) bought at least one potted plant throughout the pandemic; and/or c) you’ve seriously considered buying a plant, you just haven’t yet. If you were able to relate to at least one description above, well, you’re definitely not alone—and that’s a good thing!

Buying and taking care of plants is definitely a top Trend That Started During the COVID-19.

At this point, we think it’s safe to say there’s just no escaping it. Aside from literally livening up your space, tending to house plants has been proven therapeutic as it provides relief from the many forms of stress we’ve all felt in the middle of a pandemic. What’s more, there is strong evidence of its air-purifying properties based on this heavily quoted NASA experiment from 1989. 

According to the study, which utilized benzene and formaldehyde in its tests, it is suggested that “plant roots and their associated microorganisms are the major pathway [sic] for chemical removal.” Further in their conclusion, it is mentioned that “for the soil to be highly effective in removing indoor air pollutants, plants must be growing in this soil. Therefore, the plant is very important in removing indoor air pollution, either directly through its leaves or indirectly through the root/soil pathway.” 

Granted, this conclusion has been heavily debated since it was made in the late ’80s. (Many argue that conditions in a lab are too controlled, which leave a lot to discuss when we start considering the results for an actual home where conditions are barely in our control.

However, while we’re all in this journey of plantita-hood or plant mom-hood together, we may as well learn some of the welcome benefits our plant babies bring to our lives—particularly cleaning the air in our home. Here, we list some of the plants featured in NASA’s experiment and where you can get them to help in your quest for better quality air in your living space.

They can be mildly toxic to pets and humans, so it's important to wash your hands after touching the plant.

Rubber Plant

Bred for toughness, it will tolerate dim light and cool temperatures, making it an excellent house plant. This plant is easy to grow and is great for removing chemical toxins from the indoor environment, particularly formaldehyde.


Pothos earned high marks in a NASA clean air study for clearing the air of benzene, formaldehyde, toluene, carbon monoxide, and xylene. These vining tropicals tolerate low light, although it may make their leaves revert to solid green.
