XTREME+Plus® HC (high-capacity) self-supported pleated (SSP) air filters are specially designed for high performance and extended service life in HVAC or process air applications with low or medium dust-holding requirements. Available in three sizes (1-, 2- or 4-in).

All XTREME+Plus® HC filters achieve MERV 8 mechanical efficiency and feature a state-of-the-art media pack surrounded by a single-piece, beverage board die-cut frame. The filters can endure impact and deformation and return to their original shape, saving users time and money that is often wasted on replacing damaged wire-backed filters.
With over 250 adhesion points between the media and the frame, the XTREME+Plus® HC resists movement, bunching, and collapsing during operation thus supporting a consistent low pressure drop, balanced dust-loading, and extended service life. With no metal to warp or deform and rugged self-supported pleat technology, the filters are capable of maintaining their structural integrity even in humid or wet conditions. XTREME+Plus® HC pleated air filters are not recommended for use in applications with high temperatures or turbulent airflow conditions.
