The Environmental Relative Moldiness Index (ERMI) and the American Relative Moldiness Index (ARMI) was developed by
Dr. Steve Vesper and the United States Environmental Protection Agency.
What is the ERMI?
ERMI is an acronym for Environmental Relative Moldiness
- It was developed by scientists at the USEPA to provide a straightforward, objective and standardized
way to obtain results for indoor air quality investigations.
- The EPA is developing am ERMI ranking system based on
dust samples collected from homes across the United States.
- The ERMI will help predict the moldiness of homes.
Homes with high ERMI values have a greater chance of having a mold problem then homes with a low ERMI.
- 36 different
fungi make up the ERMI and are designated as Group I (those found in atypical, water damaged homes) and Group II (those commonly
found in all homes).
If a person is not feeling well and his or her doctor has determined that sensitivity to mold
is an issue to explore, than the ERMI analysis of the patent’s home is a good place to start.
An ERMI analysis
might help you to determine if your home is safe for visitors who might have genetic susceptibility to mold.
