Frequent Questions

Should I test or sample for mold in my home using the Environmental Relative Moldiness Index, or ERMI?

No. The Environmental Relative Moldiness Index, or ERMI, developed by U.S. Environmental Protection Agency researchers, is a research tool and is not recommended for use except as a research tool.

For more information, see EPA's Office of Research and Development Fact Sheet: The Environmental Relative Moldiness Index -- www.epa.gov/nerl/download_files/documents/Moldiness_Index.pdf.
