Air sampling is one way to find a mold source that has yet to be detected. As mold spores cannot be seen with the naked eye, an air sample is sent to a laboratory and analyzed there. Results will, not only reveal whether mold is present in the home but will also show how severe the problem is.
Air samples are generally taken in places where mold is already visible and areas that have experienced water damage or moisture intrusion. If there are musty odors in any parts of the home, which would suggest the presence of mold, it is also a good idea to take air samples in these areas.
Can air samples be taken at any time? A variety of factors can affect an air sample reading such as changes in air pressure which could affect mold spore levels and severe thunderstorms or extremely high winds. When taking an air sample, it’s best to have all doors and windows closed and any indoor-outdoor air exchangers switched off. Further air samples will also be taken after mold remediation to ensure all mold has been removed.
To summarize, then, air sampling is a good additional test for mold and can help determine mold spore levels.
