CERTIFICATION





I,
      DANIEL
      C. DUNN, certify that:





1.
      I have
      reviewed the quarterly report on Form 10-Q of ALLIED HEALTHCARE PRODUCTS,
      INC.





2.
      Based
      on my knowledge, this annual 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 report;





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





4.
      The
      registrant's other certifying officers and I are responsible for establishing
      and maintaining disclosure controls and procedures (as defined in Exchange
      Act
      Rule 13a-15(e)) for the registrant and have:





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





b)
      omitted as not yet applicable;





c)
      evaluated the effectiveness of the registrant’s disclosure controls and
      procedures and presented in this report our conclusions about the effectiveness
      of the controls and procedures, as of the end of the period covered by this
      report based on such evaluation; and





d)
      disclosed in this report any change in the registrant’s internal control over
      financial reporting that occurred during the registrant’s most recent fiscal
      quarter that has materially affected, or is reasonably likely to materially
      affect, the registrant’s internal control over financial reporting;
      and





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





a)
      all
      significant deficiencies and material weaknesses in the design or operation
      of
      internal control financial reporting which are reasonably likely to adversely
      affect the registrant'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 registrant's internal controls over financial
      reporting.
