           PURADYN EXPLAINS CHANGE IN INSTITUTIONAL OWNERSHIP SUMMARY
                  - Chairman addresses stockholder questions -

BOYNTON BEACH, FL - NOVEMBER 21, 2005 - PURADYN FILTER TECHNOLOGIES INCORPORATED
(OTCBB: PFTI) addressed recent information contained in summary reports
regarding shares of PFTI common stock owned by Quantum Industrial Partners, Ltd.
resulting in a number of phone calls from investors unnecessarily concerned that
the Company's largest stockholder was no longer designated as an institutional
investor.

Joseph V. Vittoria, Chairman, said, "Recent reports on financial websites may
have erroneously suggested that one of our stockholders, Quantum Industrial
Partners, for which Soros Fund Management LLC acts as the principal investment
advisor, had sold its 4,570,000 shares of Puradyn common stock. In fact, Quantum
Industrial Partners continues to hold all of these shares."

A recent change by the Securities and Exchange Commission (SEC) removed
Puradyn's stock from the list of securities required to be reported in quarterly
institutional investor reports on Form 13(f), effective for the quarter ended
September 30, 2005. The financial websites incorrectly inferred that the absence
of the Puradyn position from the third quarter 13(f) report filed by Soros Fund
Management LLC was due to a sale that had occurred since the prior 13(f) report,
when in fact it was due merely to the removal by the SEC of Puradyn common stock
from the list of reportable securities.

Mr. Vittoria concluded, "Quantum Industrial Partners is our largest and
longest-held stockholder and they continue to maintain their position in our
Company. The filing change has no adverse effect on the continued growth and
activity of Puradyn Filter Technologies, Inc."
