CHARLOTTE, NC — November 10, 2010 — Polypore International, Inc. (NYSE: PPO) announced today that it commenced tender offers to purchase for cash any and all of its outstanding 8¾% Senior Subordinated Dollar Notes due 2012 (the “Dollar Notes”) and 8¾% Senior Subordinated Euro Notes due 2012 (the “Euro Notes” and, collectively with the Dollar Notes, the “8¾% Notes”) pursuant to an Offer to Purchase statement dated November 10, 2010 (the “Offer to Purchase”) for a price equal to $1,002.50 per $1,000 principal amount of Dollar Notes or €1,002.50 per €1,000 principal amount of Euro Notes, which includes $972.50, with respect to the Dollar Notes, or €972.50, with respect to the Euro Notes, as the tender offer consideration and $30.00, with respect to the Dollar Notes, or €30.00, with respect to the Euro Notes, as a consent payment (collectively, the “Tender Offers”).  The aggregate principal amount of the Dollar Notes currently outstanding is $150 million (which excludes $75 million principal amount of outstanding Dollar Notes for which the Company has called for redemption on December 3, 2010) and the aggregate principal amount of the Euro Notes currently outstanding is €150 million.

In connection with the Tender Offers, the Company is soliciting consents (the “Consent Solicitation”) to certain proposed amendments to the indenture governing the 8¾% Notes that are subject to the Tender Offers to eliminate substantially all of the covenants and certain events of default and related provisions contained in the indenture.

The Consent Solicitation will expire at 5:00 p.m., New York City time, on November 24, 2010, unless extended (such date, as it may be extended, the “Consent Deadline”).  On the terms and subject to the conditions of the Consent Solicitation, the Company will pay, promptly following the Consent Deadline and the satisfaction of the other conditions contained in the Consent

Solicitation, to each holder who has validly delivered (and has not revoked) a valid consent on or prior to the Consent Deadline, $30.00 or €30.00 for each $1,000 or €1,000, respectively, in principal amount of 8¾% Notes (the “Consent Payment”).

With respect to the Tender Offers, holders of 8¾% Notes validly tendered on or prior to the Consent Deadline, if such 8¾% Notes are accepted for purchase, will receive the tender offer consideration plus the Consent Payment (the “Total Consideration”).

The Tender Offers are scheduled to expire at 5:00 p.m, New York City time on December 13, 2010, unless extended or earlier terminated (the “Expiration Time”).  Payment for 8¾% Notes validly tendered on or prior to the Consent Deadline and accepted for purchase will be made promptly after the Consent Deadline.  Holders of 8¾% Notes who validly tender after the Consent Deadline but prior to the Expiration Time, if such notes are accepted for purchase (and not earlier redeemed prior to the Expiration Time), will receive the Total Consideration less the Consent Payment.  Payment for 8¾% Notes validly tendered after the Consent Deadline and on or prior to the Expiration Time and accepted for purchase will be made promptly after the Expiration Time.

The Tender Offers are subject to the satisfaction or waiver of certain conditions as set forth in the Offer to Purchase governing the Tender Offers, including the consummation of the Company’s proposed private offering of $365 million aggregate principal amount of senior unsecured notes due 2017 (the “Senior Unsecured Notes”).  The Company intends to use the net proceeds from the offering of the Senior Unsecured Notes to repurchase the 8¾% Notes.

This announcement is not an offer to purchase, a solicitation of an offer to purchase, or a solicitation of an offer to sell securities with respect to the 8¾% Notes that are the subject of the Tender Offers or with respect to the Senior Unsecured Notes.

The complete terms and conditions of the Tender Offers and the Consent Solicitation are set forth in the Offer to Purchase that is being sent to holders of the 8¾% Notes.
