Airflow Poly Pak

By Airflow Products

The Airflow Poly Pak is an extended surface, self-supported rigid box filter engineered for medium to high-efficiency HVAC applications. Constructed entirely from impact-resistant polypropylene and injection-molded components, the Poly Pak offers exceptional durability, reduced shipping and disposal costs, and reliable filtration performance. Available in MERV 11 through 14, this moisture-resistant, non-corrosive filter is ideal for VAV systems and demanding environments.

Features

  • Lightweight Design: The 100% polypropylene construction makes the Airflow Poly Pak significantly lighter than traditional metal-framed filters. This reduces freight costs and makes it easier for technicians to install and replace in the field. Lightweight design also benefits warehousing and shipping logistics by decreasing handling strain and minimizing the risk of damage during transport or installation.
  • Rigid and Durable Construction: Designed with solid synthetic cross braces on both upstream and downstream sides, the Poly Pak offers outstanding structural integrity under varying air pressures. Unlike metal filters prone to corrosion and bending, this filter's polypropylene frame and injection-molded media separators hold their shape, resist moisture, and maintain performance throughout their service life—even in high-humidity or turbulent airflow environments.
  • Moisture and Microbial Resistance: The polypropylene materials are inherently non-corrosive and water-resistant, making the Poly Pak suitable for humid or variable climate conditions. Additionally, its synthetic components do not support microbial or bacterial growth, making it a hygienic choice for healthcare, commercial, and industrial facilities concerned with bio-contamination or long service intervals.
  • Cost-Efficient Disposal: Because the filter is compactable and primarily composed of incinerable materials (excluding the expanded metal support grid), disposal is more economical than with heavier, mixed-material filters. Reduced total weight means lower landfill charges and simplified end-of-life handling, helping facility managers control operating costs while meeting sustainability goals.
