The Hi-Flo® ex-tended-surface air filter is the only product to use Controlled Media Spacing (CMS) that minimizes pocket-to-pocket contact and keeps the pockets perfectly aligned, resulting in uniform airflow and full utilization of the media, claims the manufacturer. It is available in MERV 9, 13, and 14. The filter uses a microfine fiberglass media, and a mesh media backing provides support in turbulent or varying airflows. The product is available in a variety of configurations, including three to 12 pockets, depths of 15 to 36 inches, and up to 120 square feet of effective media area.
