Common Questions
What is the ERMI test and how does it work?
The ERMI test is a mold testing method that analyzes dust samples collected from your home. It uses DNA technology to identify and quantify specific mold species, providing a score that reflects the relative moldiness of your environment. This test is especially useful for detecting hidden mold problems that may not be visible and helps homeowners make informed decisions about remediation.
How can I interpret my EMMA test results?
Interpreting EMMA test results involves understanding the types of mold present and their potential health impacts. Each mold type is assessed based on its health risks, and the results will indicate whether remediation is necessary. It's advisable to consult with a mold expert to accurately interpret the findings and determine the best course of action.
What should I do if my spore trap results are high?
If your spore trap results indicate a high count of mold spores, it's critical to investigate further. This could mean checking for hidden moisture sources or existing mold growth in your home. Professional mold remediation may be necessary to address the issue effectively and ensure your living environment is safe.
How often should I conduct ERMI and EMMA testing?
The frequency of ERMI and EMMA testing can depend on various factors, such as previous mold issues or changes in your home's environment. Generally, homeowners in Portland should consider testing at least once a year or after any significant water damage incidents to ensure ongoing air quality and mold management.
