Four air quality indices, compared
EPA AQI, WHO 2021 guidelines, Canadian AQHI, European CAQI. Four different ways to summarize the same air.
RESET, WELL, Title 24, and air monitoring
Sensor selection can be relevant to standards-aligned workflows, but device parts alone do not confer certification, accreditation, or code compliance.
