As a consulting design engineer, I am aware that the best intentions and latest technology often fail when needed maintenance and constant monitoring are neglected. In that regard, the Airthinx is a significant development and improvement. It’s low cost, easy installation, ability to monitor multiple potential contaminants and ease of integration with BMS and specialized monitoring/alarm centers allows for an unprecedented number of devices to be installed, and the original design intent to be fully maintained, assuring high IAQ.
