Since we cannot see mold spores with the naked eye, air samples are beneficial as they can be examined in a laboratory to find out the type of mold spores that are present as well as determine the severity of the problem. Air samples are taken in any areas that have water damage or places where moisture is coming into the home as well as places where mold is already visible. If indoor air smells musty this is an indicator that mold may be developing, so this is another reason to take an air sample.
When collecting an air sample, it’s best for all doors and windows to be shut and indoor-outdoor air exchangers to be turned off. Weather also plays a role when it comes to the accuracy of the data. Severe thunderstorms or extremely high winds can affect the results of the test. Air pressure can also change mold spore levels in the air, altering the levels of them in the home.
Air samples will be taken both before and after mold remediation to compare results and ensure mold has been properly removed. As we can see, while air sampling should be done in conjunction with other tests for mold, it is a good way to find out how good the air quality is in your home.
