United States Filter Corporation

Palm Desert, California 92211

Ladies and Gentlemen:

      I am Vice President, General Counsel and Secretary to United States Filter
Corporation,  a Delaware corporation (the "Company"),  and have acted as counsel
to the Company in connection  with the  Registration  Statement on Form S-3 (the
"Registration  Statement"),  filed by the  Company  on April 3,  1997,  with the
Securities  and Exchange  Commission  pursuant to the Securities Act of 1933, as
amended,  with respect to an aggregate of up to 2,291,059  shares (the  "Selling
Stockholder's  Shares") of the Company's Common Stock, par value $.01 per share,
that  may be  offered  or sold  from  time to  time by the  selling  stockholder
identified in the Registration Statement.

      I am  familiar  with the  Registration  Statement  and have  reviewed  the
Company's  Certificate  of  Incorporation  and  By-laws,  each  as  amended  and
restated.  I have also  examined  such  other  public and  corporate  documents,
certificates, instruments and corporate records, and such questions of law, as I
have  deemed  necessary  for  purposes of  expressing  an opinion on the matters
hereinafter set forth. In all  examinations of documents,  instruments and other
papers,  I have  assumed the  genuineness  of all  signatures  on  original  and
certified  documents and the  conformity to original and certified  documents of
all copies submitted to me as conformed, photostatic or other copies.

      On the  basis of the  foregoing,  I am of the  opinion  that  the  Selling
Stockholder's   Shares  have  been  validly   issued  and  are  fully  paid  and
non-assessable.

      I  consent  to  the  filing  of  this  opinion  as  Exhibit  5.01  to  the
Registration  Statement  and to the use of my name in the  Prospectus  forming a
part thereof under the caption "Validity of Common Stock."

                                  Yours truly,

                                  /s/ Damian C. Georgino
