You already have visible mold or water damage
Investigate and address the moisture source and affected materials. Dust testing is not required to recognize that the condition needs attention.

ERMI Mold DNA Dust Test
Environmental Relative Moldiness Index · Laboratory: EnviroBiomics
$240.00
Which molds are present in this dust sample?
ERMI measures DNA from 36 selected molds in collected household dust, including 26 associated with water-damaged buildings. The findings may provide clues about past conditions and help guide decisions about further investigation.
Choose your testing package
Each package is a separate test offering. Choose one to see what it measures; collection and turnaround are selected on that product's page.
Standard ERMI
Measures 26 water-damage-associated and 10 commonly encountered selected molds. Choose collection and turnaround below.
Your package includes
- DNA measurements for 36 selected molds in household dust.
- A calculated comparative ERMI score; choose collection and turnaround below.
Additional testing compared with standard ERMI
None. This is the standard 36-mold ERMI package.
Why might you choose this?
You want information about selected molds in accumulated dust to help decide whether further building investigation may be useful.
What the results cannot establish
Dust findings cannot establish whether mold is actively growing today or whether a home is safe.
Continue with Standard ERMIERMI Plus
Choose any additional targets on the ERMI Plus product page.
Your package includes
- The standard 36-mold ERMI measurements and score.
- The collection and turnaround choices on the ERMI Plus product page.
Additional testing compared with standard ERMI
You may select up to five additional laboratory targets on the ERMI Plus product page. They are optional, are not automatically included measurements, and not every available target is a mold. The order page shows the exact current targets and charges before you add the product to the cart; selecting none does not purchase any additional testing.
Why might you choose this?
You have a specific question about one or more of the available targets beyond the standard ERMI panel.
What the results cannot establish
Extra targets do not establish current growth, airborne exposure, personal dose, or a combined health-risk score.
Continue with ERMI PlusERMI + Endotoxin
The laboratory reports mold DNA and bacterial endotoxin separately; this is not a combined exposure or health-risk score. Continue to choose collection and turnaround.
Your package includes
- The standard 36-mold ERMI measurements and score.
- A separately reported bacterial endotoxin measurement in the submitted dust.
Additional testing compared with standard ERMI
Bacterial endotoxin is measured and reported separately from mold DNA; it is not another mold target.
Why might you choose this?
You want the selected mold measurements and a separate environmental endotoxin measurement from the submitted sample.
What the results cannot establish
The two results do not form a combined exposure or health-risk score.
Continue with ERMI + EndotoxinActino + Endotoxin + ERMI
The laboratory reports mold DNA, Actinobacteria markers, and bacterial endotoxin as three distinct measurements, not a combined exposure or health-risk score. Continue to choose collection and turnaround.
Your package includes
- The standard 36-mold ERMI measurements and score.
- Selected Actinobacteria measurements.
- A separately reported bacterial endotoxin measurement.
Additional testing compared with standard ERMI
Actinobacteria and endotoxin are additional, distinct laboratory measurements; neither is part of the 36-mold ERMI score.
Why might you choose this?
You want all three separately reported types of environmental measurements from the submitted sample.
What the results cannot establish
The laboratory does not combine these findings into a home-safety or personal health-risk score.

What does ERMI testing tell you?
ERMI examines household dust for DNA from 36 selected molds: 26 associated with water-damaged buildings and 10 commonly found in indoor environments.
Dust may hold evidence of earlier conditions. The individual measurements provide context, but ERMI cannot determine on its own whether mold is growing in your home today.
What should you do with the results?
Water-damage-associated molds are detected
Look at the individual measurements alongside the building's history and observations. A physical investigation may be appropriate if concerns remain unexplained.
Your score is low or the findings are inconclusive
Do not assume there is no hidden moisture or mold problem. The result cannot rule out conditions outside the sampled dust.
How is ERMI different from other dust tests?
ERMI
Reports DNA measurements for 36 selected molds and a comparative ERMI score.
HERTSMI-2 and MOLD-10
Use narrower selected mold panels with different purposes or reporting. A broader panel is not automatically a better choice.
Product Details
What's included
- DNA-based laboratory measurements of 36 selected molds: 26 Group I and 10 Group II species or groups.
- A calculated comparative ERMI score and HERTSMI-2 information.
- The collection method and laboratory turnaround selected when ordering.
What the test measures
ERMI measures mold DNA in collected household dust. The 36 individual measurements and the calculated ERMI score are related but different report outputs; the test does not measure every indoor mold.
How to collect the sample
Choose the Swiffer or Vacuum Kit option available for your order and follow the laboratory's supplied collection instructions. The Swiffer option collects dust from suitable hard surfaces; the Vacuum Kit option collects dust with the laboratory-approved vacuum method.
Collect dust from the selected sampling area and return it as directed. A single sample does not represent an entire property.
Understanding laboratory results
Your laboratory report includes measurements of 36 selected molds and a calculated ERMI score that provides a relative comparison of mold DNA found in your collected dust.
A high ERMI score does not, by itself, establish that a home is unsafe. Likewise, a low ERMI score does not establish that a home is safe or free of moisture and mold problems.
Dust may contain evidence of earlier conditions. The score cannot determine whether a related moisture or mold condition is present now or whether a previous problem has been corrected. Understanding current building conditions may require a physical investigation of moisture sources, building materials, and visible or concealed mold growth.
Important limitations
EPA developed ERMI for research and has not validated it for routine non-research residential assessment. ERMI is not a home-safety threshold, health diagnosis, personal-dose measurement, or remediation-clearance test. The finding cannot establish what is currently in room air.
Shipping and return
Outbound kit shipping is calculated separately at checkout. Available UPS services and rates depend on your destination and the available checkout options. Follow the kit's instructions for returning the collected dust.
