What to Expect from ERMI Dust Testing

This test measures dust in your home. The test can’t tell if the dust has been there a day or a year. It can tell your allergist/medical team about the conditions inside your home, office, or vehicle.

It can tell your Health Professional about the living conditions of  your home.

The EPA (Environmental Protection Agency) created the Environmental Relative Moldiness Index (ERMI).  To create a baseline, EPA sent techs out into the low income housing projects to measure mold without regard to the condition of the building, nor the housekeeping: only consideration of the levels of mold spores in the dust that were found. The baseline had been determined. Now, whenever an ERMI test is performed in any environmental lab, the results are integrated into the EPA’s ERMI database. 

ERMI testing requires approximately 1 tbs. of dust. An ERMI test cannot tell if the mold spores in the dust came from outside of from a mold reservoir behind the refrigerator.

At American Air Testing we measure the levels of mold spores that are in your breathing zone and settled on your contents.  This way we can give your directions to clean up your living and work areas.

For more information on how our testing differs from ERMI, contact us and get an accurate answer to mold concerns for your project.

We can’t give house or work cleanup instructions from ERMI, MARIA, or ELIZA dust testing alone.
