Flowers and clean air

Indoor flowers can help decorate a home or office space, but their ability to improve indoor air quality is greatly exaggerated. Ventilation dilutes the concentration of volatile organic compounds much faster than plants can extract them from the air.

A group of scientists led by a candidate of technical sciences, associate professor of the Department of Architectural and Environmental Engineering at the University of Drexel analyzed 12 scientific studies spanning 30 years.
Based on the obtained data, they challenged the experiments of NASA, which in the 80s searched for air purification aboard spacecraft and, after a series of experiments, admitted: landscape plants are quite suitable for this. However, according to scientists from the University of Drexel, the NASA experiments and many other similar works were carried out in laboratory conditions, which do not exactly simulate real conditions. A plant in a pot was placed in an airtight chamber, a volume of a cubic meter or less, into which the target volatile substance was introduced, and its decomposition was monitored for many hours or days.
Scientists conclude that the ventilation of rooms removes volatile substances from them much more efficiently than indoor plants.

"To compete with an air purification system in a building or even just a couple of open windows in a house, it would take from 100 to 1000 plants per square meter of area," the research paper says.
