Why Air-Purifying Plants?
You might be wondering—don’t all plants purify the air? Technically, yes. Through photosynthesis, plants absorb carbon dioxide and release oxygen. But some houseplants go above and beyond, filtering out harmful chemicals like:
- Formaldehyde (found in cleaning products, furniture, and carpets).
- Benzene (in paints, plastics, and synthetic fibres).
- Trichloroethylene (in solvents and adhesives).
- Xylene and toluene (in glues and nail polish).
NASA’s famous Clean Air Study found that certain plants can remove these common indoor pollutants. So, while they won’t replace your need for good ventilation, they can absolutely help improve your indoor air quality—and your mood.
