The Environmental Relative Moldiness Index (ERMI) test has gained popularity as a way to check for mold in homes. However, many environmental scientists advise against using it due to significant limitations. Here’s why Sanieffect recommends alternative methods for a more accurate assessment of your indoor air quality.
Limitations of the ERMI Test:
- Not Designed for Routine Testing: The ERMI was created for a specific research project, not for everyday mold testing in homes. This project aimed to find connections between mold and asthma, not to determine specific mold levels.
- Unreliable Score: The ERMI score is based on comparing your home to a research study with completely different conditions. The score itself is calculated using questionable methods, making it difficult to interpret.
- Inaccurate Sampling: The ERMI test uses dust samples, which may not reflect current conditions. Additionally, the sampling methods (like Swiffer cloths) can vary widely, making comparisons unreliable.
- Doesn’t Assess Exposure: ERMI doesn’t tell you what type or amount of mold spores you’re actually breathing in. Many factors influence airborne mold levels, which ERMI fails to capture.
- Limited Use for Mycotoxins: The ERMI test doesn’t assess mycotoxin risks, which are a major concern for some homeowners. The research behind ERMI wasn’t designed to evaluate these toxins.
Below is a table and graph showing the differences in accuracy between doing the ERMI with a Swiffer cloth versus the original method of using a vacuum:
What do the numbers actually mean?
Let’s assume that the results you received back are accurate (which is a huge assumption). How do we know if they are bad or good? Simply put, we don’t. The results given are just arbitrary numbers that have never been validated. They are made up. Nobody has ever looked at the numbers to see at what point the numbers start getting ‘unhealthy’. And even if they did, it wouldn’t matter because everybody’s body is different.
What Sanieffect Recommends:
Instead of relying on the ERMI test, Sanieffect recommends a thorough visual inspection by a qualified professional. This inspection can identify potential mold sources and assess the overall indoor environment. We may also recommend air sampling or other testing methods depending on your specific situation.
Benefits of a Professional Inspection:
-
Experienced Professionals: Our inspectors are trained to identify signs of mold growth and understand the various factors that contribute to mold problems.
-
Comprehensive Assessment: We go beyond just testing to evaluate the entire indoor environment, including ventilation and moisture levels.
-
Actionable Recommendations: Based on the inspection findings, we can recommend a customized plan for addressing any mold issues and improving your indoor air quality.
