Air monitoring filters are used for the first step of air quality testing: collecting representative air quality samples for analysis.

Airborne particulate matter (PM) is a mixture of small solid particles and droplets of liquid. Air monitoring filters allow the air to flow through and trap the PM for testing and analysis.

Lab technicians use gravimetric methods to determine the volume of particulate matter as weight in a given volume of air, generally expressed in parts per million (PPM). 

After gravimetric assessment, specific follow-up tests and chemical analysis can provide detailed information on the composition of the particulate matter.

Selecting the right air sampling filter for your application is key to ensuring a representative sample, and therefore reliable test results. For example, air pollution monitoring from stacks, flues, and aerosols requires a filter that can withstand chemically harsh environments and high temperatures.
