ERMI and HERTSMI-2: What Dust Testing Can and Cannot Tell You in Kansas
ERMI and HERTSMI-2 are the dust tests most CIRS-literate physicians reference. This guide explains what they measure, how to collect a sample that means something, how to read the scores, and the honest limitations nobody selling you a kit will mention.
What Kansas changes about the picture
Continental with humid east and semi-arid west. Storm-driven roof and envelope damage plus basement humidity define the eastern half of the state.
Protocols are national; moisture is local. In Kansas, the pressure a building lives under comes from specific, predictable directions — and this protocol should be read with those directions in mind, because they decide where the risk concentrates, which assemblies fail first, and what a defensible local scope looks like.
The KS moisture drivers to read this against
- Severe storm and hail events
- Basement moisture in the humid east
- Expansive-soil foundation movement
What never changes — anywhere
What stays constant in Kansas is the discipline: find the moisture, test honestly, correct the water before the growth, remediate under containment to the sensitized-occupant standard, and let an independent verifier — not the contractor — decide when it is done.
The full protocol below covers the national playbook in depth — read it alongside the KS context above.

Kansas questions
Does this protocol change in Kansas?
The sequence never changes — locate moisture, test honestly, fix water before mold, remediate under containment, verify independently. What changes in Kansas is where the moisture pressure comes from: severe storm and hail events That determines where instruments go first and which assemblies earn suspicion.
What should Kansas households check first?
Start with the failure modes this housing stock is known for. Storm-driven roof and envelope damage plus basement humidity define the eastern half of the state. A moisture-focused assessment that ignores those patterns is guessing.
Can I get matched with a vetted provider in Kansas?
Yes — matching runs in all 50 states. Every provider is vetted on containment discipline, fine-particle competence, and willingness to be independently verified. Matching is free for households.
