The Vari+Plus VP is an extended surface filter for HVAC and turbine intake applications. The media is used in a dual layer for efficiency at MERV 15 and has a high dust-holding capacity, says the manufacturer. The company states that Dura-Tuff is exceptionally resistant to tearing, abrasion, and rough handling. According to the manufacturer, the rigid cell of Vari+Plus VP makes it well-suited to challenging conditions, including high airflow, variable air volume, turbulence, repeated fan shutdown, and high moisture. The filters feature lightweight, all-plastic construction, with no rivets, screws, faceguards, or cross bars.
