ERMI / HERTSMI dust
DNA-based dust analysis for sensitive occupants and pre-treatment baselines.
The species that matter most in Central Valley homes.
Why species matter
Not every mold needs the same response. We identify the exact species so your treatment plan, urgency, and clearance criteria match what's actually growing in your home — not a generic checklist.
Every report names the species, the count, and the action level — in plain English.
- Stachybotrys chartarum
The notorious 'black mold' — toxin-producing and tied to indoor water damage.
- Aspergillus
Common in HVAC and damp drywall; multiple species, some allergenic, some toxigenic.
- Penicillium
Fast-spreading on wallpaper, fabrics, and water-damaged materials.
- Cladosporium
Found on painted surfaces, fiberglass air ducts, and damp window frames.
- Chaetomium
A reliable indicator of long-term water intrusion in walls and ceilings.
- Alternaria
A leading allergen — frequent in showers, around windows, and under sinks.
