Term “Volatile Organic Compounds” is used to describe broad range of carbon based individual solvents and their mixtures. Health Canada (2016)  issued guidelines for only 3 individual solvents (VOC): Benzene, Toluene and Naphthalene (mothball), while 100’s of other solvents are used in any residential home and affect your health.  VOC in residential and office buildings come mostly from 4 major sources:

  • Offgassing of new construction materials: drywalls, carpets, paint, thinners, laminate, furniture and other
  • Household chemicals: cleaning supplies, “air fresheners”, perfume, inks, detergents and other
  • Food and beverages
  • Microbiological activity: mold growth

pills and capsules

In situation where chemistry and origin of VOC is unknown, the science came with a term: “comfort level”.  The meaning of the Comfort Level is a concentration of common VOC which causes no irritation or discomfort for tenants. The level is not regulated by government, but is based on scientific data.

VOC concentration of 0.5 mg/m³ (0.1-0.2 ppm) or less is commonly accepted as a comfort level and used as a criteria for clean buildings (LEED 2010. Building Design & Construction. LEED Rating System Draft, November 2010.)

Effect of VOC o air quality of your house can be explained in connection with other parameters: such as mold growth and humidity level that are tested as a part of our extensive Indoor Air Quality screening. To learn more about this service, please visit the IAQ webpage
