Trichothecenes and Stachybotrys: Context Without Panic
Stachybotrys chartarum (“black mold”) can produce trichothecenes in culture, but residential disease claims outran evidence. Dampness remediation still matters; toxin folklore is not the mechanism card for every symptom.

ERMI, Air Culture, and Mold Testing Limits
ERMI is an EPA research-origin dust DNA index—not a validated medical diagnostic. CDC does not recommend routine home mold testing; moisture inspection first.

Mold, Damp Buildings, Asthma, and Wheeze: Epidemiology
Meta-analyses link residential dampness and visible mold to ~30–50%+ higher odds of asthma and respiratory symptoms—odor counts as an exposure proxy.

MVOCs, Musty Odors, and Sick-Building Symptoms: Signal vs Hype
Microbial volatile organic compounds contribute to musty smell and can irritate—but odor alone is not a full diagnosis. Use odor as a moisture clue, not a toxin assay.

HVAC, Filtration, and Indoor Mold: What Helps and What Doesn’t
Filters reduce particles; they do not replace leak repair. HVAC can distribute spores if wet. Control moisture first, then filtration and maintenance.
