AirAlign

AirAlign is an information resource focused on indoor air quality, HVAC, environmental monitoring, and the technologies used to measure and manage indoor conditions. Its content helps readers build a practical understanding of air quality, from core concepts such as pollutants, ventilation, heating, and humidity to considerations for homes, offices, commercial buildings, production environments, and specialized facilities.

The site provides information about sensors for CO₂, oxygen, particulates, volatile organic compounds, temperature, and humidity, along with transmitters, controls, ventilation systems, air conditioners, and air-handling equipment. It also offers manufacturer information to help users research companies behind measurement, control, and HVAC technologies.

AirAlign features free interactive tools for estimating cooling capacity, air changes per hour, airflow, outdoor ventilation needs, dew point, and ventilation requirements related to CO₂ targets. These calculators are intended for both home and professional settings. The site also points visitors to relevant industry events and selected technical organizations, references, and other resources for further research.
