FOR IMMEDIATE RELEASE
- ---------------------

CUNO REPORTS RECORD THIRD QUARTER RESULTS

         o        Record third quarter Sales of $75.0 million (up 9%)

         o        Record third quarter diluted EPS of $0.44 (up 13%)

         o        Record third quarter Operating Margin of 14.9%

         o        Record third quarter Orders of $76.0 million (up 13%)

         Meriden, CT: CUNO Incorporated (Nasdaq:CUNO) today reported record
third quarter results for the period ended July 31, 2003. Sales were $75.0
million, up 9% versus the same period in 2002 and up 4% in local currency. Net
income for the third quarter increased by 13% to $7.5 million from $6.6 million
reported in the same period in 2002. Diluted earnings per share for the period
were a third quarter record $0.44, up 13% compared to $0.39 in the prior year
quarter.

         Commenting on the Company's third quarter results, Mark G. Kachur,
Chairman and Chief Executive Officer, said "Our record third quarter results
reflect the strength and resilience of our business model, particularly
considering the current challenging macroeconomic environment. Our sales growth
was led by double-digit increases in both our Healthcare and Potable Water
businesses. Our geographic diversity also contributed to our strong overall
results, as international sales




increased by 19% (up 8% in local currency), reflecting double-digit growth in
Europe, the Asia/Pacific region and Latin America."

For the first nine months of fiscal 2003, sales were a record $210.7 million, up
11% (up 7% in local currency), and net income was $19.2 million versus $16.6
million in the prior year period. Strong sales in our international operations
helped offset modest growth in North America. Diluted earnings per share were a
record $1.13, up 15% from $0.98 in the first nine months of 2002.

Commenting on business conditions and the outlook for CUNO, Mr. Kachur added,
"Our incoming orders were a third quarter record $76.0 million and our backlog
remains strong. As a result, despite the near term likelihood of continued weak
business conditions in the U.S. and Japan, we expect to achieve strong financial
results in fiscal 2003, and are comfortable with the current $1.52-$1.56 range
of analysts' EPS estimates for the year."

A conference call will be held Thursday, August 21 at 10:00 a.m. (EST) to review
the Company's third quarter financial results and business outlook. The call-in
