Plain-English notes
- ERMI vs. HERTSMI-2: ERMI looks at 36 mold species and produces a relative moldiness index; HERTSMI-2 scores 5 species. Mycometrics reports the 5 HERTSMI species and the score is calculated separately.
- Price ranges: EnviroBiomics prices vary by turnaround (standard to same-day) and kit type; we show the lowest option and the range in the notes.
- Kits and deposits: Mycometrics charges a non-refundable $50 deposit plus shipping when you order their kit, or you can send your own cloth.
- These tests don't diagnose anything. A qualified indoor environmental professional can help interpret results alongside the building's history.
