What Is ERMI Testing and How Does It Work?

ERMI testing uses settled house dust to build a detailed mould profile of an indoor environment, revealing fungal species that standard air sampling can miss. It is particularly relevant in the UAE, where sealed, air-conditioned buildings accumulate microbial reservoirs over time. This article explains the science behind ERMI, how the test is conducted, and what the results mean for property owners across Dubai and the wider Emirates.
