Most tests do not detect all the deadly molds out there. ERMI, HERTSMI, and other tests don't test for MT (Mystery Toxin) or other super toxins. The locations effect is a paradigm that has not been recognized in the mainstream mold paradigm. With Erik-style avoidance, we discourage air or dust sample tests and instead encourage a mold sabbatical. Being unmasked and paying attention to your body's response is the most accurate way to test buildings and locations.
"ERMI is inaccurate and misleading in many cases. In fact, many moldies would feel horrible in a place with ideal ERMI. That's junk test for us. Waste of time & money."
