FOR IMMEDIATE RELEASE

CUNO REPORTS RECORD FIRST QUARTER RESULTS

            -   Record first quarter Sales of $66.4 million (up 13%)

            -   Record first quarter diluted EPS of $0.32 (up 19%)

            -   Record first quarter Operating Margin of 12.5%

            -   Record first quarter Orders of $67.4 million


        Meriden, CT: CUNO Incorporated (Nasdaq:CUNO) today reported record first
quarter results for the period ended January 31, 2003. Sales were $66.4 million,
up 13% versus the same period in 2002 and up 11% in local currency. Net income
for the first quarter increased by 19% to $5.4 million from $4.5 million
reported in the same period in 2002. Diluted earnings per share for the period
were a first quarter record $0.32, up 19% compared to $0.27 in the prior year
period.


        Commenting on the Company's first quarter results, Mark G. Kachur,
Chairman and Chief Executive Officer, said "Our record first quarter results
reflect the strength and resilience of our business model, particularly
considering the current business environment. We achieved double-digit sales
growth in all three of our businesses - Potable Water, Healthcare and Fluid
Processing - and also benefited from our ongoing




cost management initiatives. In addition, the Company's geographic diversity
contributed to our strong results, as international sales increased by 21% (up
15% in local currency), led by strong growth in Europe and the Asia/Pacific
region."

        Commenting on business conditions and the outlook for CUNO, Mr. Kachur
added, "Our incoming orders were a first quarter record $67.4 million and our
backlog remains strong. As a result, despite the likelihood of continued weak
business conditions in the U.S. and Japan, we expect to achieve strong financial
results in fiscal 2003, and remain comfortable with our previous EPS guidance in
the $1.50-$1.56 range for the year." A conference call will be held THURSDAY,
FEBRUARY 20 AT 10:00 A.M. (EST) to review the Company's first quarter financial
results and business outlook. The call-in number is 1/888/273-9890 for
