EXHIBIT 31.1

            RULE 13A-14(A)/15D-14(A) CERTIFICATION OF CHIEF EXECUTIVE

Officer, Joseph V. Vittoria, Chairman and Chief Executive Officer, certify that:

1.       I have reviewed this quarterly report on Form 10-QSB for the six months
         ended June 30, 2007 of Puradyn Filter Technologies Incorporated (the
         "Company");

2.      Based on my knowledge, this quarterly report does not contain any untrue
        statement of a material fact or omit to state a material fact necessary
        to make the statements made, in light of the circumstances under which
        such statements were made, not misleading with respect to the period
        covered by this quarterly report;

3.      Based on my knowledge, the financial statements, and other financial
        information included in this quarterly report, fairly present in all
        material respects the financial condition, results of operations and
        cash flows of the small business issuer as of, and for, the periods
        presented in this quarterly report;

4.      The small business issuer's other certifying officer and I are
        responsible for establishing and maintaining disclosure controls and
        procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e),
        for the small business issuer and have:

         a)        Designed such disclosure controls and procedures, or caused
                   such disclosure controls and procedures be designed under our
                   supervision, to ensure that material information relating to
                   the small business issuer, including its consolidated
                   subsidiary, is made known to us by others within those
                   entities, particularly during the period in which this
                   quarterly report is being prepared; and

         b)       Evaluated the effectiveness of the small business issuer's
                  disclosure controls and procedures and presented in this
                  report our conclusions about the effectiveness of the
                  disclosure controls and procedures, as of the end of the
                  period covered by this report based on such evaluation; and

         c)       Disclosed in this quarterly report any change in the small
                  business issuer's internal control over financial reporting
                  that occurred during the small business issuer's most recent
                  fiscal quarter that has materially affected or is reasonably
                  likely to materially affect the small business issuer's
                  internal control over financial reporting; and

5.      The small business issuer's other certifying officer and I have
        disclosed, based on our most recent evaluation of internal control over
        financial reporting, to the small business issuer's auditors and the
        audit committee of the small business issuer's board of directors (or
        persons performing the equivalent function):

        a)        All significant deficiencies and material weaknesses in the
                  design or operation of internal controls over financial
                  reporting which are reasonably likely to adversely affect the
                  small business issuer's ability to record, process, summarize
                  and report financial information; and

        b)        Any fraud, whether or not material, that involves management
                  or other employees who have a significant role in the small
                  business issuer's internal controls over financial reporting.
