The Science Behind Indoor Plants and Air Purification
NASA Clean Air Study Findings
In the late 1980s, NASA scientists discovered that certain houseplants could remove up to 87% of indoor toxins within just 24 hours. This groundbreaking research showed that plants act as “living air purifiers,” absorbing harmful pollutants through their leaves and roots.
How Plants Absorb Toxins and Pollutants
Indoor plants filter toxins through a process called phytoremediation. They take in pollutants like formaldehyde and xylene, then break them down into harmless byproducts. Their root systems and associated microorganisms play a key role in neutralizing indoor air contaminants.
