Agence France-Presse reported that because of the new crown epidemic, air purifiers have become a hot commodity for the beginning of this fall. Classrooms, offices and homes need to purify the air of dust, pollen, urban pollutants, carbon dioxide and viruses. However, there are many brands of air purifiers on the market, and the technologies used are different, but there is no formal and unified quality standard to ensure the effectiveness and harmlessness of the products. Public institutions, schools and individual users feel at a loss and do not know how to choose.
Etienne de Vanssay, head of the French Air Environment Inter-Industry Federation (FIMEA), said that the purchase of air purifiers by people or units is mainly influenced by marketing. "In Shanghai, China, everyone has air purifiers, but in Europe we are just starting from scratch. However, this market is developing rapidly, not only in Europe, but all over the world." At present, the market size of French air purifiers is between 80 million and 100 million euros, and it is expected to reach 500 million euros by 2030. Sales in the European market reached 500 million euros last year, and in 10 years' time it will quadruple that figure, while the global market will reach 50 billion euros by 2030.
Antoine Flahault, an infectious disease expert at the University of Geneva, said that the new crown epidemic has made Europeans realize the need to purify the air: the aerosol we exhale when we speak and breathe is an important way to spread the new crown virus. Frahauert believes that air purifiers are very useful if you can't open the windows often.
According to a 2017 assessment by the Anses, certain technologies used in air purifiers, such as photocatalytic technology, can release titanium dioxide nanoparticles and even viruses. Therefore, the French government has been preventing grass-roots institutions from equipping air purifiers.
INRS and the HCSP recently released an assessment report that air purifiers equipped with high-efficiency particulate air filters (HEPA) can indeed play a role in air purification. The attitude of the French government has since changed.
