NOTE 3 - INVENTORIES

         Inventories consist of the following (amounts in thousands):



                  APRIL 30, OCTOBER 31,
                    2002       2001

                   -------    -------
                   $24,534    $24,590
                   =======    =======


         Inventories are stated at the lower of cost or market. Inventories in
the United States are valued primarily by the last-in, first-out (LIFO) cost
method. The primary method used for all other inventories is first-in, first-out
(FIFO). An actual valuation of inventory under the LIFO method can be made only
at the end of each year based on the inventory levels and costs at that time.
Accordingly, interim LIFO calculations must necessarily be based on our
estimates of expected year-end inventory levels and costs. Because these are
subject to many factors beyond management's control, interim results are subject
to the final year-end LIFO inventory valuation.

NOTE 7 - NEWLY ISSUED ACCOUNTING STANDARDS

         In June 2001, the Financial Accounting Standards Board issued
Statements of Financial Accounting Standards No. 142, Goodwill and Other
Intangible Assets. Under the new statement, goodwill (and other intangible
assets deemed to have indefinite lives) is no longer amortized but is subject to
annual impairment tests. Other intangible assets continue to be amortized over
their useful lives.

         We began applying the new rules on accounting for existing goodwill and
other intangible assets beginning November 1, 2001. The following compares
reported results to adjusted results as if the new statement was adopted
effective November 1, 2000 (in thousands, except share amounts):

         The net carrying amount of goodwill as of April 30, 2002 is $26.7
million.

         In October 2001, the Financial Accounting Standards Board issued SFAS
No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets"
effective for fiscal years beginning after December 15, 2001. SFAS No. 144
supersedes SFAS No.121, "Accounting for the Impairment of Long-Lived Assets and
for Long-Lived Assets to be Disposed Of" and provides a single accounting model
for long-lived assets to be disposed. We will adopt the statement in fiscal year
2003, which begins November 1, 2002. We are currently assessing the impact of
this new standard on our consolidated financial statements.

NOTE 8 - CONTINGENCIES

         The Company is subject to various legal actions, governmental audits,
and proceedings relating to various matters incidental to its business including
product liability and environmental claims. While the outcome of such matters
cannot be predicted with certainty, in the opinion of management, after
reviewing such matters and consulting with our counsel and considering any
applicable insurance or indemnifications, any liability which may ultimately be
incurred is not expected to materially affect the consolidated financial
position, cash flows or results of operations of the Company.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS

THREE MONTH PERIOD ENDED APRIL 30, 2002 VS. THREE MONTH PERIOD ENDED APRIL 30,
2001

NET SALES

         Net sales were $63.1 million in the second quarter of fiscal 2002
representing a 4.9 percent increase over 2001's second quarter sales of $60.2
million. This increase can generally be attributed to an increase in the unit
volume of worldwide sales. Had currency values been unchanged from the second
quarter of 2001, net sales in the second quarter of 2002 would have been $1.4
million higher, or 7.1 percent greater overall.

         The following table displays the Company's sales by geographic segment
(amounts in thousands):

         North American sales increased 11.9 percent in the second quarter of
2002 as compared to the same quarter in 2001. Strong Healthcare and Potable
Water market sales were responsible for all of the growth in North America
during this time period. The Water Group (which addresses the potable water
market) continues to record strong sales of its series of filters designed for
customers who serve various channels of distribution with final sales to US
residential consumers. Europe increased 0.9 percent as compared to the same
period in 2001, and was up 4.1 percent when expressed in local currency.
Healthcare sales were particularly strong in the quarter reflecting greater
demand in the pharmaceutical industry. Sales in Japan were down 16.1 percent as
compared to the same quarter last year, and were 8.5 percent lower when
expressed in local currency. The poor economy in Japan is largely responsible
for the lower sales demand. It is still unclear when the overall Japanese
economy, and more specifically certain segments in which we compete, will
significantly improve. Asia/Pacific sales were up 7.0 percent and increased 7.2
percent excluding changes in currency values. The majority of the increase in
Asia/Pacific is due to strong sales growth in Potable Water throughout the
region, in particular, residential products in Australia. First quarter 2002
Latin American sales were relatively flat, but were up 11.6 percent when
expressed in local currency despite the economic troubles in Argentina (see
"Argentina Peso Devaluation" in the "Other Matters" section below for a
discussion of our exposure to Argentina). The large increase in local currency
sales was supported by increased sales to the food and beverage industry which
supports such products as beer, wine, soft drinks, and bottled water.


                                       10

         The following table displays the Company's sales by market (amounts in
thousands):

Potable Water               $29,541    $25,909    14.0%     14.5%
Fluid Processing             16,499     18,148    (9.1%)    (5.7%)

                            =======    =======    ======    ======




         The slowing economies in the US and certain international markets
(primarily Japan) have impacted all of our markets to some extent; however,
Fluid Processing is the Company's most cyclical market and is most impacted by
the economic slowdown. The strength in the Potable Water market was broad
geographically, driven largely by strong overseas sales (up 9.5 percent in local
currency) and strong sales growth in North America (up 15.5 percent) associated
with OEM customers, direct marketing companies, and appliance manufacturers.
Healthcare sales increased both domestically and internationally and continue to
benefit from a continued focus by management on competitively favorable product
lines and market niches.

GROSS PROFIT

         Gross profit increased $1.5 million to $28.2 million in the second
quarter of 2002 from $26.7 million in the second quarter of 2001. Gross profit
as a percentage of net sales (gross margin) increased during that same period
from 44.3 percent in 2001 to 44.7 percent in 2002. The primary factor that
contributed to the improved gross margin in 2002 was the market mix of sales
(increased Healthcare sales which generally carry higher margins combined with
decreased Fluid Processing sales which generally carry lower margins).

OPERATING EXPENSES

         Selling, general and administrative expenses (SG&A) were up 0.6%
reflecting our continued focus on restraining discretionary spending. As further
described in Note 7, the 2002 results benefited by the elimination of goodwill
amortization ($0.3 million in the second quarter of 2001) required by the
adoption of FASB 142. Expense categories within SG&A reflected nominal increases
or decreases consistent with our cost-management strategy.
         Research, development and engineering expenses increased 10.7 percent
to $3.7 million in the second quarter of 2002, reflecting our continued focus on
the development of new products and technologies. As a percentage of sales,
research, development and engineering expenses were 5.9 percent of sales in the
second quarter of fiscal 2002 compared to 5.5 percent of sales in the second
quarter of fiscal 2001.

OPERATING INCOME

         As a result of the above, operating income increased $1.4 million, or
20.2 percent, to $8.3 million or 13.2 percent of sales in the second quarter of
fiscal 2002 compared to $6.9 million or 11.5 percent of sales in the second
quarter of 2001.


                                       11

NON-OPERATING ACTIVITY

         Interest expense was relatively flat in the second quarter of 2002
compared to the second quarter of 2001. See "Financial Position and Liquidity"
below for further discussion of the Company's cash and debt structure. As
disclosed in Note 6 to the condensed consolidated financial statements, other
income (expenses) in 2002 includes a foreign exchange loss of $0.1 million which
is primarily attributed to the devaluation of the peso in Argentina. See
"Argentine Peso Devaluation" below for a discussion of our exposure in
Argentina. Interest income was down due to lower average interest rates in 2002,
partially offset by higher average net investment levels.

INCOME TAXES

         The Company's effective income tax rate for the second quarter of 2002
was 34.5 percent compared to 36.2 percent in the second quarter of 2001. The
decrease primarily reflects the recognition of certain tax planning initiatives,
permanent tax benefits associated with the adoption of FASB 142 (see Note 7),
and a change in the mix of income attributed to the various countries in which
the Company does business.

SIX MONTH PERIOD ENDED APRIL 30, 2002 VS. SIX MONTH PERIOD ENDED APRIL 30, 2001


NET SALES

         Net sales were $121.8 million in the first six months of fiscal 2002
representing a 2.5 percent increase over 2001's comparable sales of $118.8
million. This increase can generally be attributed to an increase in the unit
volume of worldwide sales. Had currency values been unchanged from the first six
months of 2001, net sales in 2002 would have been $3.5 million higher, or 5.5
percent greater overall.

         North American sales increased 7.8 percent in the first six months of
2002 as compared to the same period in 2001. Strong Healthcare and Potable Water
market sales were responsible for all of the growth in North America during this
time period. The Water Group (which addresses the potable water market)
continues to record strong sales of its series of filters designed for customers
who serve various channels of distribution with final sales to US residential
consumers. Sales in Europe increased 6.6 percent as compared to the same period
in 2001, and were up 9.4 percent when expressed in local currency. Healthcare
sales, particularly to the pharmaceutical industry, increased during the period.
Sales in Japan were down 21.5 percent as compared to the same period last year,
and were 12.8 percent


                                       12

lower when expressed in local currency. The weak economy in Japan is largely
responsible for the depressed sales demand. Asia/Pacific sales experienced
modest growth period over period; however, sales increased 7.0 percent excluding
changes in currency values. The majority of the increase in Asia/Pacific is due
to strong sales growth in Potable Water throughout the region. Despite the
economic troubles in Argentina (see "Argentina Peso Devaluation" in the "Other
Matters" section below for a discussion of our exposure to Argentina), Latin
American sales increased 2.3 percent as compared to the same period in 2001, but
were up 21.1 percent when expressed in local currency. The large increase in
local currency sales was supported by increased penetration of all markets, with
particular strength in the food and beverage industry which supports such
products as beer, wine, soft drinks, and bottled water.

         The following table displays the Company's sales by market (amounts in
thousands):

             Total sales    $121,753    $118,772     2.5%      5.5%
                            ========    ========    =======   =======



         The weak economies in the US and certain international markets
(primarily Japan) have impacted all of our markets to some extent; however,
Fluid Processing is the Company's most cyclical market and is most impacted by
the economic slowdown. The strength in the Potable Water market was broad
geographically, driven largely by strong overseas sales (up 17.7 percent in
local currency) and steady sales growth in North America (up 10.7 percent)
associated with OEM customers, direct marketing companies, and appliance
manufacturers. Healthcare sales increased both domestically and internationally
and continue to benefit from the ongoing focus by management on competitively
favorable product lines and market niches.

GROSS PROFIT

         Gross profit increased $2.6 million to $54.4 million in the first six
months of 2002 from $51.7 million in the first six months of 2001. Gross profit
as a percentage of net sales (gross margin) increased during that same period
from 43.6 percent in 2001 to 44.6 percent in 2002. The primary factor that
contributed to the improved gross margin in 2002 was the market mix of sales
(increased Healthcare sales which generally carry higher margins combined with
decreased Fluid Processing sales which generally carry lower margins).

OPERATING EXPENSES

         Selling, general and administrative expenses (SG&A) were relatively
flat (up 1.7%) reflecting our continued focus on restraining discretionary
spending. As further described in Note 7, the 2002 results benefited by the
elimination of goodwill amortization ($0.7 million in the first six months of
2001) required by the adoption of FASB 142. Expense categories within SG&A
reflected nominal increases or decreases consistent with our cost-management
strategy.
         Research, development and engineering expenses increased 7.9 percent to
$7.1 million in the first six months of 2002, reflecting our continued focus on
the development of new products and technologies. As a percentage of sales,
research, development and engineering expenses were 5.8


                                       13

percent of sales in the first six months of fiscal 2002 compared to 5.6 percent
of sales in the first six months of fiscal 2001.

OPERATING INCOME

         As a result of the above, operating income increased $2.2 million, or
17.1 percent, to $15.2 million or 12.5 percent of sales in the first six months
of fiscal 2002 compared to $13.0 million or 10.9 percent of sales in the first
six months of 2001.

NON-OPERATING ACTIVITY

         Interest expense was relatively flat in the first six months of 2002
compared to the first six months of 2001. See "Financial Position and Liquidity"
below for further discussion of the Company's cash and debt structure. Interest
income was down due to lower average interest rates in 2002, partially offset by
higher average net investment levels.

INCOME TAXES

         The Company's effective income tax rate for the first six months of
2002 was 34.5 percent compared to 36.2 percent in the first six months of 2001.
The decrease primarily reflects the recognition of certain tax planning
initiatives, permanent tax benefits associated with the adoption of FASB 142
(see Note 7), and a change in the mix of income attributed to the various
countries in which the Company does business.

FINANCIAL POSITION AND LIQUIDITY

         We assess liquidity in terms of the Company's ability to generate cash
to fund our operating and investing activities. Of particular importance to the
management of liquidity are cash flows generated by operating activities,
capital expenditure levels, and adequate bank financing alternatives.

         We manage our worldwide cash requirements considering the cost
effectiveness of the funds available from the many subsidiaries through which we
conduct our business. We believe that our existing cash and cash equivalents
position ($25.0 million at April 30, 2002) and available sources of liquidity
(approximately $26.3 million of available, uncommitted, unused worldwide
short-term lines of credit) are sufficient to meet current and anticipated
requirements for the foreseeable future. We do not rely on commercial paper or
off-balance sheet financing arrangements for our liquidity needs.

         In March 2002, we closed on a $12 million committed unsecured credit
facility that renews annually. Borrowings under this facility are subject to
various financial covenants and bear interest at a floating interim rate based
upon LIBOR. There were no borrowings outstanding under this facility at April
30, 2002.

         We continue to invest in R&D to provide future sources of revenue
through the development of new products, as well as through additional uses for
existing products. Our efforts are spread across the various markets in which we
compete, with particular emphasis on new products and technologies in Healthcare
and the improvement in design and function of products within Potable Water. We
consider R&D and the development of new products and technologies an integral
part of our growth strategy and a core competence of the Company.


                                       14

         Likewise, we continue to invest in capital expenditures in order to
expand and modernize manufacturing facilities around the globe. We are currently
expanding manufacturing lines in Brazil and China in order to meet product
demands around the globe. In addition, new manufacturing lines and processes are
being installed in the US to benefit the Water Group, Fluid Processing, and
Healthcare operations.

         Set forth below is selected cash flow data (in thousands of dollars):

         The net cash provided by net income plus depreciation, amortization and
non-cash compensation is an important measurement of cash generated from the
earnings process. Net income plus depreciation, amortization and non-cash
compensation of $14.2 million increased 7.1 percent in the first six months of
2002 as compared to the same period in 2001 reflecting our increased sales,
gross profit, improved operating profit margin, and improved tax rate. We made
an incremental $4.0 million contribution to our US pension plans in the first
quarter of 2002 to bolster the funding and earnings capabilities of the plans.
The use of cash for accounts receivable (accounts receivable up 4.0 percent) in
2002 reflects the increased level of sales during the period. The increase in
inventory during the first six months of 2001 primarily related to the timing of
certain sales shipments.

         The increased rate of capital expenditures in 2002 primarily relates to
the continued focus on expanding and modernizing manufacturing facilities around
the globe. More specifically, we are currently expanding manufacturing lines in
Brazil and China. In addition, new manufacturing lines and processes are being
installed in the US to benefit the Water Group, Fluid Processing, and Healthcare
operations. In the second quarter of fiscal 2002, we completed a product line
acquisition in Australia for $0.5 million. In the second quarter of 2001, we
closed on two acquisitions - a product line in Australia and a distributor in
Europe for a total of $4.5 million. These acquisitions did not have a material
effect on the Company's historical financial statements nor pro forma operating
results.

         Due in part to our increased stock price, during the first six months
of fiscal 2002, 106,923 stock options were exercised (net of shares used to pay
individual taxes) providing $1,184,000 in net cash proceeds.

OTHER MATTERS

ARGENTINE PESO DEVALUATION

         A significant devaluation in the Argentine peso took place in our first
quarter of 2002. We have a branch located in Argentina that accounted for less
than 1% of consolidated net sales in 2001. Because this branch's operation is
not material to our consolidated results, it has only a minimal impact on our
overall results of operations. See "Market Risk Disclosures" below.

WAR ON TERRORISM AND ITS IMPACT ON CUNO

         Other than the general economic downturn, the terrorist attacks on
September 11, 2001 did not materially impact our business. Going forward, our
exposure in the Middle East is very limited - fiscal 2001 sales were less than 2
percent of total worldwide sales and we have no fixed assets in the region.

         Partly as a result of the terrorist attacks, the cost of insurance has
risen substantially and the availability of insurance has become more
restrictive. We maintain insurance coverage with such deductibles and
self-insurance as considered adequate for our needs. Such coverage reflects
market conditions (including cost and availability) existing at the time it is
written and the relationship of insurance coverage to self-insurance varies
accordingly. We consider the impact of these changes as we continually assess
the best way to provide for our insurance needs now and in the future.

ESTIMATES AND ASSUMPTIONS

         In preparing financial information, we use estimates and assumptions
that may affect reported amounts and disclosures. Estimates are used when
accounting for depreciation, amortization, employee benefits, contingencies and
asset valuation allowances (including those for bad debts and allowances for
deferred income tax assets). For example, in determining annual pension costs,
we must estimate future rates of return on plan assets and future compensation
rates. We are also subject to various risks and uncertainties that may cause
actual results to differ from estimated results, such as changes in the
industry, overall economy, competition, foreign exchange rates, litigation, and
legislation.

MARKET RISK DISCLOSURES

         The overall objective of our financial risk management program is to
seek a reduction in the potential negative earnings effects from changes in
foreign exchange and interest rates arising from business activities. We manage
these financial exposures through operational means and by utilizing available
financial instruments. Practices may change as economic conditions change.

Foreign Currency Risk
         Our earnings and cash flows are subject to fluctuations due to changes
in foreign currency exchange rates. We utilize forward foreign exchange
contracts to hedge specific exposures relating to intercompany payments, certain
firm sales commitments and anticipated, but not yet committed, intercompany
sales (primarily parent company export sales to subsidiaries at pre-established
US dollar prices) and other specific and identified exposures. The terms of the
forward foreign exchange contracts are generally matched to the underlying
transaction being hedged, and are typically under one year.


                                       16

         Because such contracts are directly associated with identified
transactions, they are an effective hedge against fluctuations in the value of
the foreign currency underlying the transaction. All of our foreign exchange
contracts are accounted for at fair value based on readily available market
price quotations. We generally do not hedge overseas sales denominated in
foreign currencies or translation exposures. Further, we do not enter into
financial instruments for speculation or trading purposes.

         We utilize bank loans and other debt instruments throughout our
worldwide operations. To mitigate foreign currency risk, such debt is generally
denominated in the underlying local currency of the affiliate. In certain
limited and specific circumstances, we will manage risk by denominating a
portion of debt outstanding in a currency other than the local currency.

FORWARD LOOKING INFORMATION

         The Securities and Exchange Commission encourages companies to disclose
forward-looking information so that investors can better understand a company's
future prospects and make informed investment decisions. Also, we want to
provide stockholders and investors with more meaningful and useful information
and therefore, this quarterly report describes our beliefs regarding business
conditions and the outlook for the Company, which reflects currently available
information. These forward looking statements are subject to risks and
uncertainties which, as described in Management's Discussion and Analysis in the
Company's Annual Report on Form 10-K for the year ended October 31, 2001, could
cause the Company's actual results or performance to differ materially from
those expressed herein. We assume no obligation to update the information
contained in this quarterly report.
