Perma Pure was founded in 1972 by Jack Kertzman to provide tubing solutions for gas drying and humidifying applications.

Nafion™ polymer was developed as an improved material for electrolysis membranes in chlor-alkali production, where salt solutions are separated for production of chlorine and sodium hydroxide. While its extreme corrosion resistance was required for this application, Nafion™ polymer’s very selective permeation by water was a serendipitous development.

Perma Pure purchased the exclusive license from DuPont for the technology to manufacture tubing from Nafion™ polymer in 1978 and remains the sole manufacturer of Nafion™ tubing. In 1992, Jack Kertzman retired and Halma Holdings, the North American arm of London-based Halma plc, acquired Perma Pure. Under Halma’s direction, Perma Pure has expanded its operations to include a wide range of gas sample conditioning products. Today, Perma Pure dominates the worldwide market for drying breath and is rapidly expanding its share of the high-performance gas conditioning market.
