Exhibit 99.1

(NYSE Listed: PPO) Third Quarter 2009 Supplemental Financial Information

2 These materials include "forward-looking statements". All statements other than statements of historical facts included in these materials that address activities, events or developments that we expect, believe or anticipate will or may occur in the future are forward-looking statements including , in particular, the statements about Polypore International's plans, objectives, strategies and prospects regarding, among other things, the financial condition, results of operations and business of Polypore International and its subsidiaries. We have identified some of these forward-looking statements with words like "believe," "may," "will," "should," "expect," "intend," "plan," "predict," "anticipate," "estimate" or "continue" and other words and terms of similar meaning. These forward-looking statements are based on current expectations about future events affecting us and are subject to uncertainties and factors relating to our operations and business environment, all of which are difficult to predict and many of which are beyond our control. Many factors mentioned in our discussion in these materials will be important in determining future results. Although we believe that the expectations reflected in our forward-looking statements are reasonable, we do not know whether our expectations will prove correct. They can be affected by inaccurate assumptions we might make or by known or unknown risks and uncertainties, including with respect to Polypore International, the following, among other thing s: the highly competitive nature of the markets in which we sell our products; the failure to continue to develop innovative products; the loss of our customers; the vertical integration by our customers of the production of our products into their own manufacturing process; increases in prices for raw materials or the loss of key supplier contracts; our substantial indebtedness; interest r ate risk related to our variable r ate indebtedness; our inability to generate cash; restrictions related to the senior secured credit facilities; employee slowdowns, strikes or similar actions; product liability claims exposure; risks in connection with our operations outside the United States; the incurrence of substantial costs to comply with, or as a result of violations of, or liabilities under environmental laws; the failure to protect our intellectual property; the loss of senior management; the incurrence of additional debt, contingent liabilities and expenses in connection with future acquisitions; the adverse impact on our financial condition from past restructuring activities; the failure to effectively integrate newly acquired operations; the absence of expected returns from the amount of intangible assets we have recorded; the adverse impact from legal proceedings on our financial condition; natural disaster s, epidemics, terrorist acts and other events beyond our control; and economic uncertainty and the current crisis in global credit and financial markets. Because our actual results, performance or achievements could differ materially from those expressed in, or implied by, the forward looking statements, we cannot give any assurance that any of the events anticipated by the forward looking statements will occur or, if any of them do, what impact they will have on Polypore International's results of operations and financial condition. You are cautioned not to place undue reliance on these forward looking statements, which speak only as of the date of these materials. We do not undertake any obligation to update these forward looking statements in these materials to reflect new information, future events or otherwise, except as m ay be required under federal securities laws.
