What it finds

HERTSMI-2 tests your dust for the DNA of five mold species most often found after long-term water damage and turns them into a single score. It is narrower than ERMI and costs less: a focused answer to one question, how much of the water-damage group is in the dust.

  • Aspergillus penicillioides
  • Aspergillus versicolor
  • Chaetomium globosum
  • Stachybotrys chartarum
  • Wallemia sebi

In the box

  • Swiffer dust cloth (pre-cut, collection-ready)
  • Labeled collection bag
  • Prepaid return shipping mailer
  • Step-by-step illustrated instructions
  • Your report by email, with your HERTSMI-2 score

When to order

After a leak or a flood has been fixed and cleaned, to see where the water-damage species stand, or as a lower-cost re-check after a high ERMI. It is a screen, not a clearance test; if a contractor or a sale needs formal clearance testing, talk to us first.
