LIFEGARD™ Media Bed Monitor, PureAir Filtration’s groundbreaking technology released last year, is reshaping air quality management with real-time data and predictive insights.

This newly issued patent protects critical innovations that enable real-time monitoring and predictive data analysis of chemical filtration media life — marking another major advancement in air quality management. It builds on PureAir’s earlier patented monitoring technologies, U.S. Patent No. 10,132,740 (issued November 20, 2018, “Media Bed Monitoring Device and System”) and U.S. Patent No. 10,801,946 (issued October 13, 2020, “Electronic Monitoring of Gas Adsorbent Media Bed”), further strengthening the company’s leadership in the development of gas-phase filtration monitoring systems.

The LIFEGARD™ Media Bed Monitor features externally mounted sensors that continuously track media bed performance. It provides both wired and wireless data transmission, early-warning predictive alarms, and supports proactive maintenance scheduling—enabling users to plan media changeouts in advance and minimize unplanned downtime.

Originally introduced as the Electronic Bed Monitor (EBM and EBMv2), the system was rebranded as LIFEGARD™ media bed monitor to reflect its enhanced functionality and its vital role in protecting mission-critical environments and equipment.
