The Parker Ultra II® Pocket Filter is a durable, high-capacity green colored MERV 8 filter designed for commercial and industrial HVAC systems requiring consistent performance in demanding environments. Constructed with graduated denier polyester media, the Ultra II® captures a wide range of airborne particles while maintaining low resistance and long service life.
Each filter features a self-sealing, sewn pocket design reinforced with an internal wire frame, preventing air bypass and ensuring dependable performance without external supports. The self-supported construction allows vertical or horizontal installation while maintaining pocket integrity and balanced dust loading for energy-efficient operation.
Rated for continuous use up to 225°F (107°C), the Ultra II® filter is ideal for air handling units, built-up banks, side-access housings, and paint booth applications. Available in two- or three-pocket configurations with 15" or 20" depths, the Ultra II® delivers long-lasting, leak-free air filtration through Total Filtration Services (TFS).

Media
Ultra II pocket filters are made with graduated denier polyester fibersUpstream layer features larger fibers with a more open structureDownstream layer contains finer fibers which are more densely arranged; improves depth loadingDownstream layer is also needled; forms a final barrier to catch dirt particlesMedia receives a heavy application of a pressure sensitive tackifier; helps retain collected dirt particles
