Quick FactsDescription and BenefitsBest ValueCI Supraloft® line of Panel Filters are one of the industry’s best values in filtration. CI uses polyester media produced in CI-owned and operated facilities to make panel filters. In fact, CI’s environmentally responsible panel filters are manufactured with recycled products whenever possible. The CI Supraloft® Panel Filters are available in a wide variety of filtration performance options to meet the needs of today’s varied and challenging HVAC environments.

Removes ContaminantsCI Supraloft® Panel Filters help to improve indoor air quality and remove contaminants from HVAC environments. Each panel filter is engineered to protect both expensive HVAC equipment and workers from dirty air and its damaging effects. The CI Supraloft® Panel Filters will also extend the life of costly secondary filters. Equally important, the user-friendly filters are lightweight, durable and easy to install.

Self-Sealing to Prevent Air BypassWith their self-sealing design, the CI Supraloft® Panel Filters prevent air bypass and increase efficiency performance. Each panel is heat-sealed around a sturdy internal grid that provides durability and structural integrity. The CI Supraloft® Panel Filters use a progressive density fiber structure and incorporate a non-migrating tackifier for optimum filter performance in airflow, efficiency and depth loading. The filter’s synthetic media is unaffected by ambient temperature changes or excess humidity.

Various ConfigurationsCI Supraloft® Panel Filters are available in both single panel and linked configurations, and are a suitable replacement for all commonly used pre-filters. The filters provide the best performance in both pre-filtration and standalone applications.
