MICRO SHIELD® Mini Pleat Filters

CI MICRO SHIELD® Mini Pleat Filters are available in a variety of sizes and efficiency ratings are perfect for air intake systems; the extended surface area these filters provide improve airflow and have need less frequent change outs.

CI MICRO SHIELD® Mini Pleat Filters utilize technologically advanced filtration media that incorporates a dual-layer, gradient-density fiber structure resulting in exceptionally low airflow resistance, reducing both energy and operating costs, yielding best in class performance. They are available in 2” and 4” depths and range up to MERV 15 with V-cell constructed mini pleats ranging up to MERV 16.

2” MICRO SHIELD® Mini Pleat Filter – MERV 15


CI 2" MICRO SHIELD® Mini-Pleated Filters are an economical choice for extended surface, high-efficiency air filtration requirements. Each filter utilizes a technologically advanced media that incorporates a dual-layer, gradient-density fiber structure that results in exceptionally low airflow resistance, at the highest efficiency levels – reducing both energy and operating costs.

These high-performance filters will improve indoor air quality and remove contaminants from HVAC environments. CI 2" MICRO SHIELD® Mini-Pleated Filter is engineered to protect both expensive HVAC equipment and workers from dirty air and its damaging effects. The user-friendly filter is also fully incinerable, lightweight, durable and easy to install.

The self-supported 2" MICRO SHIELD® Mini-Pleated Filter utilizes a geometrically formed pleat pack. Each pleat pack is further strengthened with a glue-bead separator. The pack is then sealed into a heavy-duty, moisture-resistant kraft board frame. Each stage of the assembly process is quality controlled to ensure the filter’s performance, consistency and durability. These design and construction features combine to produce the best all-around performance in airflow, efficiency and dust-loading uniformity. Columbus Industries’ 2” Mini-Pleated Filters are available in MERV 15.

Looking for LEED certification? The CI 2" MICRO SHIELD® Mini-Pleated Filters are the perfect solution if you want to specify or upgrade your current filtration to meet LEED certification requirements. With these high-performance filters, your facility can gain points toward LEED certification – without incurring large operating cost increases. The CI 2" MICRO SHIELD® Mini-Pleated Filter meets efficiency standards outlined in the LEED program for new construction and existing buildings.
