We spend more than 80% of our time indoors. The constant improvement of the effectiveness of insulation systems means it has become essential to renew the air regularly in order to prevent pollutants from stagnating inside our buildings.

Analyse air intérieur laboratoire Essonne

Indoor air refers to all the air inside closed buildings (offices, establishments open to the public, private homes, etc.) that are not subject to occupational exposure.

In this type of environment, air pollution may be suspected if there are cases of recurrent headaches, respiratory irritations, bad smells, and also following recent works. We can measure this pollution using an indoor air analysis.

Quad-Lab has developed different packs to cater to this variety of issues:

  • Pack analyse air Quad-Lab laboratoire EssonneThe Indoor Air Pack: used to analyse the compounds most commonly found inside buildings. It can be used following works, or if the occupants are experiencing unpleasant phenomena.
  • The HQE Pack is used to analyse the compounds recommended by the HQE standard when the building is delivered or when it is operating.
  • Odour Pack: used to analyse the compounds responsible for unpleasant smells.
  • The ERP Pack: a regulatory pack (France) for establishments open to the public (French decree 2011-1727 of 2nd December 2011).

Quad-Lab also has an extensive catalogue of analyses, amongst which feature:

  • aldehydes, including formaldehyde*, present in 100% of housing and offices,
  • monocyclic aromatic hydrocarbons (MAH), including benzene* (carcinogen), found in most furnishing, building and decoration products,
  • chlorinated solvents such as tetrachloroethylene which are often released by carpeting, dry-cleaned clothing, or rugs),
  • terpenes, including limonene, and alpha-pinene, contained in deodorants, household cleaning products and fragrances,
  • acetates, for example the butyl acetate contained in paints and wood flooring.


*Quad-Lab is COFRAC accredited for formaldehyde and benzene.

The scope of the accreditation can be viewed on http://www.cofrac.fr/annexes/sect1/1-1578.pdf using accreditation reference N° 1-1578.

You are a private individual ?

Did you know that indoor air is 5 to 10 times more polluted than outdoor air ?

If we can filter the water we drink, filtering the air we breathe is not possible. In fact, furniture, household cleaning products, paints and many other standard consumer goods release volatile organic compounds that pollute our indoor air.
