Formaldehyde Measurement

The largest emissions of Formaldehyde are associated with its manufacture and subsequent use, natural emissions are lower. General sources of Formaldehyde are as follows:

  • Sterilisation.
  • Preservatives in food, cosmetics and pesticides.
  • Adhesives.
  • Vehicles without catalytic converters.
  • Insulation, furniture and carpets.
  • Cigarette smoke.
  • Forest fires and natural decay.


We provide two sampling options for sampling Formaldehyde in ambient air. The first is our tube which is used for active (pumped) sampling over a few hours to identify levels of Formaldehyde; alternatively, we can provide a passive option through the use of UMEX badges for sampling from 12 hours – 7 days. Concentrations can be measured in the low parts per billion (ppb) range and above.

The pumped tubes are ideal for determining formaldehyde levels as part of a BREEAM air quality assessment.


Potential implications of Formaldehyde pollution:

  • Respiratory effects – eye, nose and throat irritation.
  • Indoor air monitoring to identify causes of health symptoms.
  • Monitoring following the installation of new furnishings or products.
  • Personal exposure monitoring during manufacture.
