HERTSMI-2 is the most accurate. Often houses will pass air spore tests but HERTSMI-2 will catch the problem. It isn't necessary to do an ERMI - that tests for ALL molds in your house. You only need to test for Mycotoxin producing molds, which the HERTSMI-2 does.

This is the kit I recommend for testing for mold: https://www.envirobiomics.com/product/hertsmi-2/

Only costs $130. Buy the Swiffer kit. Vacuum is not as accurate. Clean the whole house, then wait 2-4 weeks, then use the Swiffer kit to collect dust that has settled in the bedrooms and living room. Don't do kitchen or bathrooms.

Interpreting a HERTSMI-2:

0-8: Excellent

9-10: Good

11-15: Possibly dangerous. Deep clean the whole house, especially locations that are rarely cleaned and have settled dust like the tops of ceiling fans, door frames, blinds, etc. Wait 2-4 weeks and retest. If the score is still 11 or above, you have a significant mold problem that needs to be found and remediated by professionals.

16-50: Dangerous. You have a significant mold problem that needs to be found and remediated by professionals.
