20 Best Air-Purifying Plants (And How To Keep Them Alive)

From reducing stress levels to improving your focus, houseplants have many benefits. But did you know that some species of air-filtering plants can even prevent you from getting liver damage, kidney disease, and cancer?

Volatile organic compounds, or VOCs, are used to make most home products—furniture, paint, carpets, and even the construction materials used to make the home itself. Over time, VOCs like formaldehyde, benzene, ammonia, and toluene are off-gassed into the air and can cause serious health issues.

Typical electrostatic air filters can't remove VOCs, but luckily, there's an aesthetically pleasing, natural, NASA-proven way to return your air to a better state: stocking your home with air-purifying plants. Read on to learn more about the 20 best air-purifying plants you can put in your home, as well as care instructions for each species according to the experts at the University of Georgia's College of Agricultural and Environmental Sciences.
