Poly Shield XI Media


Fiber Bond’s Poly Shield XI media delivers MERV 11 performance when tested in accordance with ASHRAE 52.2-2012. It is the ideal media choice for applications requiring highly efficient filtration. The media is manufactured with Dustlok Composite Adhesive, an aggressive adhesive that has the ability to absorb particles and continuously renew its effectiveness.

Spor-Ax antimicrobial keeps filter media free from mold, mildew, algae, and 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.


  • Poly Shield XI 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 Composite Adhesive enhances the filter’s performance throughout its service life
  • Clean change-outs as a result of dust-cake retention
