puraDYN Files Notice of Voluntary Delisting from American Stock Exchange; Cites Long-Term Needs of Company and Stockholders

puraDYN Filter Technologies Incorporated (AMEX:PFT)
announced today that the Company has submitted to the American Stock
Exchange notice of its intent to withdraw from listing its common
stock, and has filed an application for delisting with the Securities
and Exchange Commission (SEC) pursuant to Section 12(d) of the
Securities Exchange Act of 1934.
   puraDYN's Board of Directors considered several factors in making
this decision, including:

   --  Determination that the Company, as previously notified on
        April 28, 2005, would not be able to timely comply with the
        Exchange's ongoing financial compliance listing standards
        under Section 1003(a)(i) and (ii) of the Exchange's Company
        Guide.

   --  Subsequent notice received from the Exchange on June 24, 2005
        that the Company is not in compliance with Sections 301, 711
        and 713(a)(ii) of the Company Guide, the consequences of which
        would require the Company to either 1) limit the amount of
        financing of its previously announced private offering or 2)
        incur additional costs and defer receipt of the financing
        pending stockholder approval as required by the Exchange's
        rules.

   --  The expense of maintaining the listing of the Company's common
        stock on the Exchange, including the cost for Exchange-listed
        shares of complying with requirements relative to the
        Sarbanes-Oxley Act of 2002, which has had, and is expected to
        have, a significant negative effect on the Company's cash flow
        and earnings.

   --  Continued compliance with the listing rules and requirements
        of the Exchange and Sarbanes-Oxley demand significant
        attention and time from Company management and personnel that
        could be dedicated to developing business and pursuing
        strategic opportunities.

   Joseph V. Vittoria, Chairman, said, "After careful deliberation,
our Board of Directors concluded that the needs of the Company and its
stockholders are better served at this time and the foreseeable future
by delisting puraDYN from the Exchange and trading its common stock on
the OTC Bulletin Board.
   "In conjunction with senior management, we believe that this
action will result in material savings to the Company and allow our
team to focus solely on our business operations."
   puraDYN continues to be required to file reports with the SEC
under Section 13 of the Securities Exchange Act of 1934, including
quarterly and annual reports, and its common stock is expected in the
ordinary course to be included for quotation on the OTC Bulletin
Board.
   The Company will also continue to engage the services of its
independent registered public accounting firm, Daszkal Bolton LLP, to
perform quarterly and annual audits of the Company's financial
statements and maintain many of the corporate governance improvements
the Company achieved during its tenure on the Exchange.
   puraDYN will announce the new trading symbol and effective date of
trading when received.
