When monitoring indoor air quality (IAQ), it is important before we pick up any piece of monitoring equipment, that we have a method and protocol to tell us what we are monitoring, how and where we sample and with what equipment.

There are a number of good iaq guides which have devolved from ASHRAE, there are also indoor air quality specification with part F of the building regulations

We recommend as a basic monitoring scheme that the following would be need to be monitored,

A good quality, professional grade monitor for this typically costs around £1800 to purchase or

Real time data logged using accredited devices

additional monitoring may be :

  • VOC’s- Total voc’s at ppb level
  • specific voc’s  – Formaldehyde

Particulate and fine particulate

real time dust monitor
Dust monitor
  • pm10
  • pm2.5
  • possibly ultrafine particulate (nano particulates)

depending on the type of room being monitored, it is also important to consider

  • Airflow – along the floor area, around the head area
  • microbio sampling for different bacteria  Aspergillus, Cladosporium, Penicillium

other considerations

  • light
  • decor
  • noise and vibration
