Industry Intelligence | Brief of the World Filtration Institute (WFI)

This issue covers Johnson Controls, ESCO Technologies, the U.S. Air Force, and more.

EXECUTIVE SUMMARY

The filtration industry continues to accelerate across key sectors. The single-use bioprocessing market is set to triple to $15.5B by 2035, driven by biologics and advanced therapies. At the same time, residential filtration demand is rising due to water quality concerns, while regulatory action on PFAS is expanding federal involvement in water treatment. Innovation and sustainability remain central, with breakthroughs like Moringa-based microplastic removal and $9.5B in energy savings from Johnson Controls. Strong financial results from ESCO and advancements in smart filtration systems further highlight a market moving toward efficient, sustainable, and decentralized solutions.
