               NOTES TO CONSOLIDATED FINANCIAL STATEMENTS



The accompanying unaudited condensed financial statements have been
prepared in accordance with the instructions to Form 10-Q and do not
include all the information and footnotes required by generally accepted
accounting principles for complete financial statements.  In the opinion
of management, all adjustments (consisting of normal recurring accruals)
considered necessary for a fair presentation have been included.  

Operating results for the three months ended March 31, 1996, are not
necessarily indicative of the results that may be expected for the year
1996.

These statements should be read in conjunction with the financial
statements and related notes included in the Company's Annual Report to
shareholders and Form 10-K for the year ended December 31, 1995.

Sales

Sales of $33,229 for the quarter ended March 31, 1996 increased 23.7%
from the first quarter of 1995.  The increase occurred primarily in
capital equipment, which represented 61% of total sales for the first
quarter of 1996.  Sales of membrane products and cartridge filters also
showed good growth over the prior year.

Quarterly sales include sales of Western Filter, acquired in
October 1995, but do not include any sales from Desalination Systems,
Inc. (DESAL).  It is anticipated that the previously announced merger
with DESAL will be completed in the second quarter of 1996.

Gross Margin

Gross margin decreased from 44.3% of sales in the first quarter of 1995
to 40.8% of sales in the first quarter of 1996.  Average gross profit
margins are below the prior year first quarter due in large part to a
change in product sales mix.  This is a result of recent acquisitions
and sales strategy changes.  

Gross margins also continue to be affected by increased costs that have
not been fully passed on to our customers.  Certain raw materials such
as stainless steel and plastic continue to be above anticipated costs. 
Also, some non-recurring costs were incurred in the move to newly
completed expansions of the Minnetonka and Phoenix facilities.

Operating Expenses

Operating expenses decreased from 31.0% of sales in the first quarter of
1995 to 27.7% in the first quarter of 1996.  Selling, general and
administrative expenses, and research, development and engineering
expense were lower as a percentage of sales in the first quarter of 1996
than in the corresponding period of 1995.  

The rate of growth in operating expense slowed to 10.4%, compared to the
sales growth rate of 23.7%.  It is believed that the investment in sales
and marketing during the prior years is producing results, and recent
investments in office automation are showing returns in higher
productivity.

Other Income

Other income decreased by $281 from the first quarter of 1995 to the
first quarter of 1996.  The decrease results from lower interest income
on a lower investment portfolio, and the inclusion in 1995 of a non-
recurring $200 recovery from an insurance policy.  

Income Taxes

The effective tax rate for the first quarter 1996 is 31.0% based on the
forecast for the full year.  This compares to 31.4% in the corresponding
period of 1995.  

Net Income

Net income for the quarter was $3,162, as compared to $2,800 for the
first quarter of 1995.  Net income per share was $0.25 per share, an
increase of 14% over the $0.22 per share reported for the same quarter
last year.  

Liquidity and Capital Resources

As of March 31, 1996, the Company had cash, cash equivalents and
marketable securities of $25,465 versus $30,668 at December 31, 1995. 
The current ratio was 3.0 at March 31, 1996, as compared to 2.9 at
year-end 1995. 

Inventory remained relatively constant during the first quarter of 1996,
compared to year-end 1995.

In the first quarter of 1996, the Company expended $6.1 million on
capital improvements, primarily for the expansion of the Minnetonka and
Phoenix facilities, for office automation and for new product tooling.

The Company believes that its current cash and investments position, its
cash flow from operations, and amounts available from bank credit will
be adequate to meet its anticipated cash needs for working capital,
capital expenditures, and potential acquisitions during the foreseeable
future.

                            OTHER INFORMATION



Item 5.  Other Information

         The Company announced in December 1995 the execution of an
         agreement in principle to merge with Desalination Systems Inc.
         (DESAL) in a stock transaction.  The outstanding shares of
         DESAL will be exchanged on a share-for-share basis for the
         Company's common stock.  The transaction is structured to
         qualify as a tax-free exchange and a "pooling-of-interests" for
         accounting and financial purposes.  At current market prices,
         the value of the transaction is approximately $30 million.  The
         transaction is expected to add over $20 million to Osmonics'
         1996 sales.

         The transaction will require the approval of a definitive
         merger agreement by both companies, regulatory approvals, and
         the satisfaction of customary closing conditions.  Preparation
         of the required documents is continuing, and the transaction is
         expected to be completed in the second quarter of 1996.
