Ranking of air-purifying houseplants backed by NASA's Clean Air Study: Spathiphyllum, Dracaena, Pothos and more — which toxins they absorb and how many you need per room.
要点总结
Ranking of air-purifying houseplants backed by NASA's Clean Air Study: Spathiphyllum, Dracaena, Pothos and more — which toxins they absorb and how many you need per room.
A 1989 NASA study called the "Clean Air Study" explored how plants might improve air quality in enclosed space station environments, demonstrating that certain plants can absorb and break down harmful substances.
The study measured the removal of volatile organic compounds (VOCs) including formaldehyde, benzene, trichloroethylene, xylene, and ammonia by plants cultivated in sealed chambers.
Plants purify air through two main mechanisms:
Important caveat: This study used sealed chambers, and results may not directly translate to typical residential settings. The contribution of plants to air quality improvement is not disproven, but relying solely on plants for air purification has limitations.
Formaldehyde: Found in plywood, flooring, adhesives, paints, and curtains. Concentrations rise in newly built or renovated homes, contributing to sick building syndrome.
Benzene: Found in paints, varnishes, adhesives, and cigarette smoke.
Trichloroethylene: Used in cleaning agents and degreasers.
Healthy specimens are essential for maximum air-purifying potential. Bri-Choku connects you with specialist growers for quality plants and pre-purchase advice on placement and care.
