Indoor Air Quality Monitoring – using low cost sensor and standard methods

As people return to work after covid lock-down, many were concerned as to how clean their office was. They deployed many types of monitoring methods.

For a number of organisations this meant, operating in a field that they new little about and purchasing equipment on line that was neither suitable for the application, had no validation(Mcerts)  or calibration.  They had no knowledge on a reporting standard that they required to meet, nor what that would mean

Other groups of people are seeking to get a certification for their building, such as Breeam, Well, LEED

When perform Indoor Air Quality(IAQ) we can define a number of key pollutants that we can monitor. These include:

NO2- Nitrogen Dioxide

PM10, PM2.5- These are particulate matter (PM) with a size of , either less than 10 microns (PM10) or less than 2,5 microns

CO2 -Carbon Dioxide

CO, carbon Monoxide

Temperature and relative humidity (RH)

Formaldehyde – This is a basic set of monitoring that can be done within a building.

Of equal importance is : What are the sources of these pollutants and how do we mitigate for them.

Where do we sample from ( our sampling location ) and for  how long and at what rate?

What do are results mean and what do we compare them with . can provide monitoring equipment that is accredited – provides consultancy to monitor for these
