CUNO history

In 1926 Cuno entered the market for filtration products, applied to automotive and industrial uses.

The Cuno Foundation was established in 1947 by Charles H. Cuno with an initial contribution of $104,584.

In 1958 Cuno Engineering expanded to European markets through a joint venture with Olin Mathieson Chemical Corporation.

Adapting industrial technology to home use, AMF Cuno introduced the AP400 Lime Aid Water Conditioner for water heaters in 1975.

In 1983 AMF added the Molecular Separations Division to design, manufacture, and market a new product.

New leadership at AMF narrowed the company's focus to leisure and sporting goods, leading to AMF's divestment of Cuno in 1986.

1988: The acquisition of Water Factory Systems strengthens Cuno in the consumer market.

Marketing to specific markets overseas led to increased demand for industrial filters, prompting construction of a new manufacturing facility in Japan in 1989.

Cuno relocated, consolidated, and expanded its water purification systems manufacturing at one 120,000-square-foot facility in Enfield, Connecticut, purchased in late 1992.

A proprietary nylon membrane played a significant role in development of new products; sales related to these high margin filters increased 100 percent in 1996.

By May 1997 CUNO launched nine products for worldwide distribution.

In 1999, however, sales of water purification and filtration products rose by 37.4 percent, to $87.7 million, as the introduction of a new line of water filters, primarily sold to appliance manufacturers, positively impacted North American sales.
