Indoor air testing
We spend up to 90% of our time indoors, whether in the home, at school or work. Older buildings often struggle with controlling mould, whereas modern buildings are often poorly ventilated. Both can result in the build-up of indoor pollutants - exposing occupants to concentrations which can be hazardous to health. If you want to measure if the concentrations of air pollution in a given environment are safe for the health of the occupants, then you might want to consider having an air test done.
There are many instruments available for testing air quality. These can be divided into two main classes, depending upon whether the pollutant to be measured is particulate or gaseous.
