Distinct Dual Density provides maximum dust loading. The course open structure of the white, air entering layer is designed for depth loading. The orange, dense downstream layer prevents finer dirt particles from passing through the filter media.

Unique Dustlok Adhesive uniformly coats the fibers in the downstream layer during the formation of the filter media. Dustlok is an integral part of total media - not a post application.

Dutlok Will Not Dry Out or Migrate due to the non-volatile chemical composition of its adhesive formulation.

Dustlok Renews Its Effectiveness by absorbing dust particles into the adhesive, thus trapping them onto the surface of individual fibers.

Operating Temperatures Up To 200°F with no adverse effect in performance.

Spor-Ax Antimicrobial is a biocide that effectively controls growth of mold, mildew, algae, and fungi on filters. Fiberbond filters with Spor-ax do not support microbial growth. Spor-Ax will not off gas, migrate or leach into the air stream.

Dual-Ply Dustlok Performance Independent laboratory testing using ASHRAE Standard 52.2 (method of testing general ventilation air cleaning devices for removal efficiency by particle size) classified one inch Dustlok as MERV 8.
