Cuno: Yesterday & Today

CUNO was a world leader in the design, manufacture, and marketing of a comprehensive line of filtration products for the separation, clarification, and purification of fluids and gasses. Its proprietary products included uses in the healthcare, industrial, and drinking water markets. The Company operated a total of eight manufacturing facilities in the United States, Europe, Japan, Brazil, and Australia, and had sales offices throughout the world.  Today the CUNO name is owned by 3M Inc. which does not currently use the CUNO name in commerce.

A History of Ingenuity

CUNO was the surname of the company founder, Charles Cuno, who began manufacturing operations in 1912 for a variety of products, primarily for automobiles, in Meriden, Connecticut. The Company grew and developed new products for filtration that included engine and hydraulic metal filters. Filtration and separation became the primary focus during the 1960's through 1980's. From 1986 to 1996, CUNO was the Fluid Purification business of Commercial Intertech. In September of 1996, CUNO Incorporated became a publicly listed company (NASDAQ: CUNO) following the distribution of one share of the new company's stock for every common share of Commercial Intertech stock held by shareholders of Commercial Intertech
