Are air purifiers supposed to track pollutants inside high schools effective? According to the study carried out on Covid-19 particles in real conditions by Virpath and Virnext laboratories supported by Lyonbiopôle, the answer is positive.
Installed in secondary schools in the region, the air purifiers with a HEPA H13 filter would retain 99.2% of the ultrafine particles present in the air and 99.9% with higher quality (H14). Then, once trapped, the Covid-19 particles would last for about 48 hours in the HEPA filter and then disappear.
Laurent Wauquiez, President of the Region, is very satisfied with this study funded by the region for € 184,000. “Air purifiers should be included in the national high school strategy.” For two months, the labs worked to discover the performance of the purifiers for a conclusive result.
A first in Europe
“This scientific demonstration is the first in Europe. It is an extremely strong response. Air filtration works, it is a hope for everyone. This operation could also work for restaurants ”, announces the president. He then continues: “When we started our deployment of air purifiers in secondary schools and schools, we were criticized that there was not enough scientific evidence on the effectiveness of this device. Today, thanks to this study, we can verify the usefulness of this tool in the fight against Covid-19 ”, he emphasizes.
“Therefore, we will intensify our infiltration devices and I will officially refer to the Ministry of National Education so that air purifiers are included in the national high school strategy,” he concluded.
It is a very important step that has been achieved. When we began our deployment of air purifiers in high schools and schools, we were criticized that there was not enough scientific evidence on the effectiveness of this device. Today, thanks to this study, we can verify the usefulness of this tool in the fight against Covid-19 ”, he emphasizes.
A 10 million euro envelope
By freeing up € 10 million last year to install air purifiers, Laurent Wauquiez wanted to make the AURA region an example when it came to managing Covid-19 in secondary schools. Numerous scientific studies establish that the air is one of the most important vectors for the spread of the virus.
Half of the endowment (5 million) corresponded to public and private secondary schools in the territory, the other half was destined to co-finance this equipment with other communities in schools but also in media libraries, libraries, nursing homes.
