An illustrious history of ingenuity

Founded by Charles Cuno in 1912, CUNO began operations in Meriden, Connecticut, manufacturing a variety of products, primarily for automobiles. CUNO then moved on to develop 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. While CUNO was the Fluid Purification business of Commercial Intertech, from 1986 to 1996, CUNO Incorporated became a publicly listed company (NASDAQ: CUNO) in September 1996.

August 1, 2005 witnessed the acquisition of CUNO by 3M – providing customers worldwide – the combined advantage of advanced materials innovation from 3M and the separation and filtration experience of CUNO.
