The advice of Alain Cornille, medical advisor in indoor environment

Alain Cornille is medical advisor in indoor environment (CIAM) for eight years.
He intervenes in a patient suffering from respiratory disorders or allergies at the request of his doctor. It carries out a health check thanks to the research of the potential sources of pollutants and allergens. An intervention is billed around 300 euros.
According to this professional, air purifiers equipped with filters are effective. A CIAM may recommend that patients obtain one to improve their quality of life if they have a disorder.
However, it strongly advises against photocatalytic devices. By destroying the fine particles present in the air, the ionizers emit smaller particles which, they are even more dangerous for the health (irritations of the membranes and the mucous membranes, respiratory problems, asthma...).
