Medical infection-control and dialysis-water filters sit alongside commercial filtration products for foodservice equipment and ice machines. The business combines a hollow-fiber water-technology base with a dialysis-market heritage.
Medical products span infection-control microfilters and ultrafilters, plus dialysis-water filters. Commercial water-filtration products include carbon-based and carbon-free offerings for foodservice equipment and ice machines.
Rooted in hollow-fiber water technology and a dialysis-market heritage, the business addresses proactive and emergency water management in medical and commercial settings. It also provides water-quality education as part of its offering. Operations are based in South Orange, New Jersey.
Medical product claims are FDA-regulated, and dialysis-filter models are FDA 510(k)-cleared. The business depends on continuing product performance and manufacturing arrangements across medical and commercial applications.
