Environmental dust testing
ERMI vs HERTSMI-2
Compare two tests for mold DNA in settled indoor dust. Choose by the scope of the panel and what you need in your report.
ERMI Mold Test
Measures 36 mold species or groups in settled dust. The report includes mold DNA findings, an ERMI score and HERTSMI-2 information. Choose it when you need a broader panel or an ERMI score.
HERTSMI-2
Measures five mold species in settled dust. The report includes findings for those species and HERTSMI-2 scoring. Choose it when your sampling plan specifies a focused panel.
Plan your timeline
Check current prices and kit options on the product page. Allow time for kit delivery, sample return and laboratory processing.
Testing beyond mold DNA
ERMI MycoTox 50™ combines mold DNA analysis with a targeted chemical panel. Actino Dust® analyzes settled dust for actinobacteria DNA.
How to use the report
Review the findings alongside building conditions and sampling context. The U.S. EPA developed ERMI as a research tool and does not recommend it for routine home mold testing. An environmental dust report cannot diagnose illness or certify remediation.
