4” MICRO SHIELD™ Mini Pleat Filter – MERV 14 & 15 CI 4" 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. The CI 4" 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 4" MICRO SHIELD™ Mini-Pleated Filter utilizes a geometrically formed pleat pack. Each pleat pack is further strengthened with rigid, mechanical pleat separators. The pack is then sealed into a heavy-duty, moisture-resistant kraft board or plastic 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’ 4” MICRO SHIELD™ Mini-Pleated Filters are available in MERV 14 and 15.
