Air-Purifying Plants That Improve Indoor Air Quality

Air-purifying plants remove volatile organic compounds, formaldehyde, benzene, and other indoor pollutants through leaf absorption and microbial root activity. NASA's Clean Air Study popularised these species as a natural indoor-air improvement.

Research on phytoremediation shows that many common houseplants extract measurable amounts of airborne toxins when grown in sufficient density. The species below are flagged air-purifying in PlantoScan's data, aligning with the species on NASA's Clean Air Study and its later research follow-ups.

Every species below links to its full plant care guide on PlantoScan, covering watering, light, soil, propagation, and toxicity.
