You have likely seen the headline: “If you have this plant in your house, then you have good luck!” or “…then you are breathing cleaner air!” These catchy phrases circulate widely on social media and lifestyle blogs, often attributing mystical, health-related, or spiritual benefits to common houseplants.
While such claims are engaging, they rarely tell the whole story. Without knowing which specific plant is being referenced, it is impossible to evaluate the statement accurately. However, examining a few popular examples reveals a helpful pattern: many plant myths contain a grain of truth, wrapped in layers of exaggeration.
Here is what science and tradition actually say about some widely celebrated houseplants.
If You Have a Snake Plant (Sansevieria)
The claim: “…then you have cleaner air!”
The reality: Research from NASA’s Clean Air Study did find that snake plants can remove trace amounts of certain indoor pollutants, such as formaldehyde and benzene. However, the study was conducted in sealed laboratory chambers, not typical homes. To achieve air-purifying effects comparable to a mechanical air filter, you would need an impractical number of plants—estimates suggest more than ten per square foot.
The balanced take: While a single snake plant will not transform your indoor air quality, it is undeniably low-maintenance, resilient, and visually striking. Its presence adds greenery, which studies show can support mood and reduce stress. That is a meaningful benefit, even without the superlatives.
