ERMI and HERTSMI-2: What Dust Testing Can and Cannot Tell You in New Mexico
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 New Mexico changes about the picture
Arid to semi-arid with summer monsoon. Flat-roofed adobe and territorial styles concentrate risk at roof drainage and parapet details.
Protocols are national; moisture is local. In New Mexico, 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 NM moisture drivers to read this against
- Monsoon roof and parapet leaks
- Evaporative cooler moisture
- Flat-roof ponding
What never changes — anywhere
The sequence holds in New Mexico exactly as it does everywhere else: locate the moisture, characterize the exposure with testing collected correctly, fix the water before touching the mold, remediate under verified containment, fine-clean, and verify independently. Every shortcut this industry sells is a reordering of that list.
The full protocol below covers the national playbook in depth — read it alongside the NM context above.

New Mexico questions
Does this protocol change in New Mexico?
The sequence never changes — locate moisture, test honestly, fix water before mold, remediate under containment, verify independently. What changes in New Mexico is where the moisture pressure comes from: monsoon roof and parapet leaks That determines where instruments go first and which assemblies earn suspicion.
What should New Mexico households check first?
Start with the failure modes this housing stock is known for. Flat-roofed adobe and territorial styles concentrate risk at roof drainage and parapet details. A moisture-focused assessment that ignores those patterns is guessing.
Can I get matched with a vetted provider in New Mexico?
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.
