But what can be done against this pollution? There are some very efficient plants that are crazy about these pollutants.


Plants “breathe” through a phenomenon called photosynthesis which allows them to naturally reduce CO2. But in addition to this known mechanism, certain plants and flowers purify the surrounding air. This is called “bio-purification” or “purification by the living”.

Plants that can do this purify the air by storing toxic chemicals in their cells or by transforming them. Scientists then use the term phytoremédiation, from the Greek phyto which means plant and remediation which means rehabilitation.

Which plants to choose?

Unfortunately, not all plants and flowers have this air purification function against toxic products. Here is a selection of ten plants, shrubs and flowers that will be beneficial for your interior.



Native to China, Russia and Japan, the chrysanthemum appreciates temperate climates. It is advisable to place it in your office or in your living room. It can also be planted outdoors, but will need to be brought in for frosts.

The Chlorophytum purifies the air of benzene, formaldehyde, carbon monoxide, toluene and xylene found inside our homes. Pollutants mainly present in cleaning products.
