Maximum Service Life


Fiber Bond’s Dustlok media delivers three-stages of filtration. The first stage (white side) of the media is designed for depth-loading, capturing particulate as air enters. The second stage (orange side) is designed to stop dirt from passing through the media. Finally, Dustlok composite adhesive delivers the third stage of performance. The aggressive adhesive has the ability to absorb particles and continuously renew its effectiveness.

Spor-Ax Antimicrobial Keeps Filter Media Free From Mold, Mildew, Algae & Fungi

Fiber Bond’s Spor-Ax antimicrobial is part of the manufacturing process, not a costly, post-application. The elimination of microbial growth reduces resistance and extends service life.

  • Dustlok media is manufactured with Spor-Ax antimicrobial to effectively control the growth of mold, mildew, algae and fungi on the filter media.

  • Fewer change-outs reduce filter expense, labor cost, disposal fees and landfill waste.

  • Due to its unique composition, Dustlok’s performance continually increases right up to the point of change-out.
