LifeAire Systems of Bethlehem was originally formed more than 10 years ago to create an air purification system for in vitro fertilization. Now its air purification systems are being used by hospitals and health care systems and is being transformed into a tool against COVID-19.

LifeAire Systems, an Upper Macungie Township company that creates in-duct air purification systems that remove airborne pathogens such as COVID-19, is looking to produce more. The company developed the technology for the in vitro fertilization industry and installed it in its first hospital a couple years ago.
