We spend more than 80 percent of our time indoors. With the ongoing development in the efficiency of insulation systems, it has become necessary to replenish air on a regular basis in order to prevent pollutants from stagnating in our buildings.
Indoor air refers to any air in covered structures (offices, public institutions, private homes, etc.) that is not exposed to occupational hazards.


Quad-Lab provides a wide range of indoor air analyses, including:
- Aldehydes, including formaldehyde, found in 100% of homes and offices;
- monocyclic aromatic hydrocarbons (HAM), including benzene (carcinogenic), found in most furniture, construction and decoration products;
- chlorinated solvents such as tetrachloroethylene, often released from carpets, dry-cleaned clothing or carpets);
- terpenes, including limonene and alpha-pinene, contained in deodorants, cleaning products and fragrances;
- acetates, for example butyl acetate used in paints and parquet flooring.
Health Impact:
Indoor air pollution can trigger allergic responses, such as rhinitis and conjunctivitis, as well as respiratory symptoms like asthma exacerbation. There may be immediate effects, such as carbon monoxide (CO) poisoning, which in the most severe cases can result in death within a few tens of minutes. There are potentially long-term consequences, including the start or exacerbation of cardiac and respiratory problems.
Quad-Lab is Cofrac accredited on formaldehyde and benzene.
The scope of accreditation can be found on www.cofrac.fr under the accreditation reference N° 1-1578.
