This year, the start of the school year is marked by the coronavirus epidemic. If barrier gestures are the order of the day in schools, some establishments have had to close their doors for suspicion of COVID-19. Jean-Michel Blanquer, french Minister of National Education, announced that 28 schools and 262 classes had closed. Due to the peculiarity of this year, we have decided once again to look at air quality in schools.
Air quality in classrooms has always been a concern but has been overlooked for a long time. In 2017, Dr Cristina Paunescu from France published a report on daily contact with children. In the study of ultrafine particles of pollution, the researchers used portable miniDISC and AE51 sensors to monitor the air quality of 96 schoolchildren in Paris and its suburbs. The results showed that students were exposed to the most polluting particles in schools. Indoor air pollution is five times more polluted than outdoor air, causing a lot of damage to children's health. Even if doors and windows are securely closed, small polluting particles can still enter the classroom through gaps in doors, windows, and structures. In addition, the concentration of people in confined and poorly ventilated rooms increases the risk of encountering viruses. In fact, the more a space is confined, the less the air and therefore the virus concentration is diluted.
TEQOYA paid close attention to the quality of air in classrooms long before the onset of the epidemic, and has made continuous efforts. In November 2019, with the support of municipal authorities, we collaborated with Veolia and Vinci for data measurement, cooperated with ENTRA for the installation and tested our latest purification technology in a nursery in the town of Plaine in Greater Paris.
Results : After 4 months of comparison, tests and data show that in classrooms equipped with TEQOYA purifiers, air pollution was reduced by three times.
Tests were also carried out against the H1N1 virus (influenza A).The results are promising knowing that it is a virus close to COVID-19. Indeed, after three test cycles carried out at different initial virus concentrations and humidity values, the controlled ionization reduced the viral titer by approximately 75% compared to the non-ionized control. It is consistent to conclude that air purifiers have the ability to reduce the concentration of COVID-19 in the air, with a level of performance comparable to those measured on viruses and bacteria. Many medical practices and companies have approached us, especially during this period of crisis that we are going through. Dental centers, osteopathy and physiotherapy practices... many have adopted TEQOYA air purifiers and tell us about them :
My eyes were stinging because of the pollution. The ionizer reduced that quickly. I breathe better and the pollution sensor allows me to see how fast the action is. Beyond the fire, I also had The objective is to protect myself from the pollution of daily life and to bring a real plus to my practice, which I already air as much as possible. People who come are also afraid to catch the covid in the waiting room, and I have For fear of contaminating them, an air purifier can provide additional reassurance.
After looking for and trying out several devices for our meeting rooms, I was convinced by the design and environmental values of TEQOYA air purifiers, and especially by the one that can be installed in a ceiling light and makes sense in a presentation room for 60 people! [...] Moreover, the air purifiers seem to improve the working capacity! Students and professionals in training are taking courses here. With the devices, the recovery of each one is faster. We are so convinced by the devices, we even brought to a sick employee in his hospital room to help him recover faster!
