	People spend a significant amount of time indoors, especially within their homes, where they are exposed to a large number of microbes which can have important implications for their health. With the advancement of sequencing technologies, it is now possible to study the indoor microbiome and how it affects the inhabitants. House dust is the main reservoir of microbial taxa in the domestic environment. The amount and diversity of the microbiome in dust affect health, especially because dust-born microbes and their products suspend into the air and produce a significant indoor exposure by breathing.

			People spend a significant amount of time indoors, especially within their homes, where they are exposed to a large number of microbes which can have important implications for their health. With the advancement of sequencing technologies, it is now possible to study the indoor microbiome and how it affects the inhabitants. House dust is the main reservoir of microbial taxa in the domestic environment. The amount and diversity of the microbiome in dust affect health, especially because dust-born microbes and their products suspend into the air and produce a significant indoor exposure by breathing.
