ERMI Testing: Maybe Not for You

Mold growth can be a big concern for many property owners. Mold can cause health issues including respiratory problems, allergies, headaches, and more. The Environmental Relative Moldiness Index (ERMI) was used by environmental testing experts as a tool to detect and measure indoor mold contamination.

However, in recent years, ERMI mold testing has become outdated. St. John Environmental Consulting uses state-of-art technology when it comes to testing your home or business for the presence of mold. So let’s explore the reasons why ERMI mold testing is out of fashion, and what alternatives are available for homeowners who want reliable and professional mold testing.

ERMI Testing - Not a reliable indicator of mold levelsThe Environmental Relative Moldiness Index (ERMI) is a test developed by the Environmental Protection Agency (EPA) to estimate the amount and type of mold present in a home. However, the EPA now asserts that the ERMI test is intended for research purposes only and should not be used as a commercial or residential testing method.

  • It is not a reliable indicator of mold levels. The ERMI test measures the amount of mold DNA in dust samples. However, the presence of mold DNA does not mean that there is active mold growth in your home. Mold DNA can be present even if there is no mold growth, or if the mold growth is very small.
  • It does not identify the source of mold growth. The ERMI test does not tell you where the mold is growing in your home. If you have an ERMI test that shows elevated mold levels, you will need the expert services of St. John Environmental Consulting to identify the source of the mold growth.
  • It is expensive and time-consuming. ERMI testing requires specialized equipment, trained professionals, and expensive laboratory analysis. The average cost of ERMI testing can go as high as $1000, which is not affordable for many homeowners. In addition, ERMI testing can take weeks or even months to get results, which can delay any necessary remediation efforts.
