By lowering pollutants, houseplants can improve indoor air quality. Phytoremediation takes place when plants absorb and digest contaminants through their leaves and roots. Houseplants mitigate air pollution in these ways:
Remove Volatile Organic Compounds (VOCs): Paints, carpets, and cleaning products release VOCs.
These chemicals can harm health. Spider plants, snake plants, and peace lilies absorb and break down VOCs.
Plants produce oxygen from carbon dioxide through photosynthesis. This is basic plant biology, yet it improves indoor air quality by raising oxygen levels.
Water vapor from transpiring plants regulates ambient humidity. Mold and airborne infections can be prevented by adequate humidity.
Particle Matter Filtration: Plants filter dust and allergies from the air. Plant leaves and stems can trap particles, stopping them from circulating indoors.
Some houseplants absorb and counteract airborne biological pollutants. The Boston fern (Nephrolepis exaltata) removes formaldehyde from the air.
Houseplants can improve indoor air quality, but they cannot replace ventilation and other air quality management methods. Regular upkeep, watering, and lighting are essential for houseplants to filter the air.
