Synthetic Pocket Air Filters

The Aerostar® SoniQ® Pocket is constructed with a non-shed, moisture resistant, synthetic media that consists of a layered and blended melt-blown polypropylene able to capture small particles from the air stream. The ultrasonic welding process provides a product with no stitch holes to prevent any possible air leakage. Available in a wide range of sizes, depths, and number of pockets.


  • Open throat design for optimum air flow
  • Low initial pressure drop and superior dust holding capacity
  • Galvanized steel header and J-channels for filter strength

The Aerostar® SoniQ® Pocket filter is constructed with moisture-resistant ultrasonically welded media. This synthetic media consists of strategically layered and blended melt-blown polypropylene fibers fastened to a non-shed, high-density polypropylene backing. This design creates a dual-stage filtration effect with the final layer capturing the smaller particulate from the air stream. The patented ultrasonic welding process allows us to manufacture a product that has no stitch holes in the media and provides a substantial increase in effective surface area.

Vertical separators are incorporated into each pocket to effectively channel air throughout the media to prevent excessive turbulence and allow even contaminant loading throughout the life of the filter. The header is constructed of 26-gauge galvanized steel with rolled edges to provide rigid support to the filter face and allow for easier handling.


The SoniQ Pocket filter offers high-efficiency filtration while maintaining low resistance to air flow. The non-shed media eliminates fiber migration downstream and the ultrasonic welding provides lower resistance with no disruption to the integrity of the filter. The open throat design and the precise pocket spacing produces a product that is aerodynamically balanced and provides excellent all-around performance.


HEPA filters are used in hospitals, pharmaceuticals, and micro-electronic manufacturing, laboratories, aerospace, food processing, cleanroom environments, and more. From ceiling to floor applications and HVAC to airplane ventilation we can help. Special framing and sealant applications are also available in a variety of sizes and efficiencies.
