               PURADYN RECEIVES NOTICE OF NON-COMPLIANCE FROM AMEX
             - Company to submit plan of action to retain listing -


BOYNTON BEACH, FL - MAY 4, 2005 - PURADYN FILTER TECHNOLOGIES INC. (AMEX: PFT)
announced today that it has received a letter of notice from the Staff of the
American Stock Exchange (AMEX) indicating that the Company is below certain of
the Exchange's continued listing standards. Specifically, as set forth in
Sections 1003(a)(i) and (ii) of the AMEX Company Guide, the Company has
sustained losses from continuing operations and/or net losses in two out of its
three most recent fiscal years with stockholders' equity of less than $2
million, and losses from continuing operations and/or net losses in three out of
its four most recent fiscal years with stockholders' equity of less than $4
million.

The Company has been given the opportunity to submit a plan to the AMEX
outlining actions it has taken, or will take, over the next 18 months that will
bring it into compliance with continued listing standards. The Company intends
to submit a compliance plan to AMEX by May 31, 2005 and the Company's Common
Stock continues to trade on AMEX.

If AMEX accepts the plan, the Company may be able to continue its listing during
the plan period of up to 18 months, during which time the Company will be
subject to periodic review to determine whether it is making progress consistent
with the plan. If the plan is not accepted by AMEX, or if accepted but the
Company is not in compliance with continued listing standards at the end of the
18-month period, or has not made progress consistent with the plan, the AMEX may
still elect to initiate delisting proceedings with regard to the Company's
Common Stock.

"As outlined in our 2004 earnings release, the Company is currently in the
process of raising capital. This capital is necessary to meet the ongoing
listing requirements of AMEX as well as providing the funding needed to advance
our business plan." said Joseph V. Vittoria, Chairman.
