The truth is usually more nuanced than the headline. But that doesn’t mean houseplants aren’t wonderful. They are. Just maybe not for the reasons TikTok says.
Let me walk you through five popular houseplant claims—what’s real, what’s exaggerated, and what you should actually believe.
🌿 1. If You Have a Snake Plant (Sansevieria), Then You Have… Better Air Quality?
The Claim:
Snake plants “purify the air” and produce oxygen at night, making them the perfect bedroom plant. Some sources claim they remove toxins like benzene, formaldehyde, and trichloroethylene.
The Science (Real Talk):
This claim comes from a famous 1989 NASA study that tested houseplants’ ability to remove volatile organic compounds (VOCs) from sealed chambers. Snake plants performed well.
Here’s the catch: The NASA study was conducted in small, sealed containers—not living rooms. To achieve the same level of air purification in a typical bedroom, you would need hundreds of plants per square foot. One snake plant on your nightstand is not scrubbing your air in any meaningful way.
