How To Test Indoor Air Quality: A Guide To Air Sampling Methods
To test indoor air quality, it is necessary to collect a sample of the air. This can be done with a variety of air sampling equipment, but the most common method is to use a passive sampler. Passive samplers are small, inexpensive devices that are placed in the indoor environment for a period of time, usually several weeks. The sampler collects air pollutants on a filter, which is then analyzed in a laboratory. A more accurate but more expensive option is an active sampler that draws air through a filter using a pump.
