Every home has dust. But have you ever asked yourself, “What is in my dust?” It turns out your dust holds clues to what might be going on in your home. Dust can harbor mold spores, mycotoxins and other contaminants. The Environmental Relative Moldiness Index (ERMI) test is a testing method that analyzes dust in the home for mold spores and fragments. 

In today’s mini class, we discuss the Environmental Relative Moldiness Index (ERMI).  

You’ll learn:

  • How to take an ERMI sample
  • Strengths of ERMI samples
  • Limitations of ERMI samples
  • When to use ERMI samples
  • How to read lab reports
  • And more!

A few important reminders about testing:

  • There are no perfect tests.
  • Each test has specific purposes and limitations.
  • Testing should answer a question you have about your home and influence your next steps.
  • Ultimately, testing is just one piece of the puzzle. Any testing should be done in combination with a thorough visual investigation of the entire home taking into account the history of the home and the health of the people in it. A good Indoor Environmental Professional (I.E.P.) can help you with this process. For more information on the role of an I.E.P., check out our resources, here, here, and here.
