Back to school : virus and air quality

This year's back-to-school season is marked by the coronavirus epidemic. While barrier gestures are the order of the day in schools, some institutions have had to close their doors due to suspicion of COVID-19. Jean-Michel Blanquer, Minister of National Education, announced that 28 schools and 262 classes had closed. Due to the evolution of the COVID-19 epidemic, we decided once again to focus on air quality in schools.

Air pollution and viruses in classrooms

In 2017, Dr. Cristina Paunescu publishes a report on daily exposure to ultrafine particles and carbon black in children. In this study, researchers monitored the air quality of 96 schoolchildren in Paris and its suburbs. The results showed that students are most exposed to pollution at home and at school.

What are the sources of pollution in classrooms ?

The cleaning products used to clean classrooms emit volatile organic compounds (VOCs) that are harmful to health. In addition, in many classrooms, floor coverings are made of plastic and release phthalates, other carcinogenic chemicals. To this we can add that school furniture, such as chairs and desks, is made with materials that emit formaldehyde, classified as an inhalation carcinogen.

What are the health risks for children ?

This pollution can cause a lot of damage to children's health because their lungs are still growing and developing. Air pollution increases the risk of allergic rhinitis, neurodevelopmental disorders (attention deficit hyperactivity disorder) and can also cause certain cancers (and be a factor in obesity).

What is the link between viruses and pollution?

The concentration of individuals in confined and poorly ventilated rooms increases the risk of crossing viruses such as COVID-19. Indeed, occupying a confined and poorly ventilated space for one or more hours could be the common element in the majority of COVID-19 infection situations. Another preliminary study has detected that Sars CoV-2 could even be carried by PM10 particles - similar in nature to PM2.5, but slightly larger. Researchers at several Italian universities suggest that the virus could spread more widely on airborne particles.

Our solutions to improve indoor air quality

We fight against indoor pollution

TEQOYA paid particular attention to air quality in classrooms long before the outbreak began, and has made continuous efforts to clean up the school environment. In November 2019, with the support of the municipal authorities, we collaborated with Veolia and Vinci to measure the data. We cooperated with ENTRA to install and test our latest air purification technology in a crèche in Aubervilliers.

After 4 months, the tests showed that in classrooms equipped with TEQOYA air purifiers, air pollution was divided by 3.The device diffuses negative ions in large quantities throughout the space and thus charges the polluting particles, down to the finest ones, to stick them on the surfaces. The TEQOYA air purifier is light, compact and easy to install. The equipment, completely silent, protects the respiratory health of the child without any interference with his studies and his life.

We fight against viruses

The respiratory virus of COVID-19 is close in size to the viruses and bacteria for which the ionizers were designed and tested in the laboratory. Indeed, we have already performed several tests and the results show an efficiency rate of about 90% for the elimination of bacteria present in the air during the different tests :

Tests have also been conducted against the H1N1 virus (influenza A). A 75% viral load reduction performance was verified three times. 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 several companies have approached us during the crisis period we are going through. Dental centers, osteopathic and physiotherapy practices... have adopted TEQOYA air purifiers and talk to us about it :


Information on air quality and news from TEQOYA

How does an air ionizer work?

November 27th 2021

Natural environments are rich in negative ions. This is precisely the principle on which the air ionizer is based on. However, do you know how this technology manages to capture the pollution particles contained in the indoor air to purify your home?


Are air purifiers effective against viruses, especially the coronavirus COVID-19

#Virus and microorganismes   #L'essentiel  

In December 2019, a respiratory virus of the Coronavirus family appeared in the Wuhan region of China and has now spread to all continents.


What is eco-responsibility?

October 27th 2021

Purifying indoor air while protecting your health and the planet is possible! Say goodbye to filters and make way for negative ions: choose an eco-responsible air purifier that will easily reduce energy and resource consumption.
