Fiberbond Poly Shield Panels

Poly Shield XI MERV 11 panels are designed with a unique, high-denier air entering layer of media that provides superior dust holding.

One panel delivers 3-stages of filtration: The first stage designed for depth-loading; the second stage captures particulate and keeps it from filtering through the media; and the third stage, Dustlok composite adhesive, absorbs particles and continuously renews its effectiveness.

These panels are manufactured with Spor-Ax antimicrobial to effectively control the growth of mold, mildew, algae and fungi on the filter media and exceeds new construction phase requirements for LEED certification program.

Poly Shield XI panels combine MERV 11 efficiency with the benefits of dualdensity media. The unique media design will provide superior dust holding and long service life. Manufactured with Dustlok Composite Adhesive, an aggressive adhesive that has the ability to absorb particles and continuously renew its effectiveness.

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.
