Is indoor air more polluted than outdoor air? Absolutely—10 times out of 10. In fact, poor indoor air quality ranks among the top five health risks, thanks to stagnant toxins, chemical off-gassing from furniture (like formaldehyde), and outdoor contaminants like pollen, bacteria, and mold.
Luckily, certain houseplants can naturally filter these pollutants, improving your home's air quality. Drawing from NASA's Clean Air Study, these nine resilient varieties are nearly indestructible, perfect even for beginners without a green thumb.
