The Neo-Pure Whole House Sediment Filter, Model MBGC-45200-05, is a 4.5"-Diameter cartridge, and is compatible with large-capacity whole-house filter housings such as the 3M/Aqua-Pure AP801-2 and the Pentair-Pentek Big Blue #20. Incoming water is filtered via depth filtration through a thick shell of 100% meltblown polypropylene media about a rigid polypropylene core. 

The grooved filter membrane yields larger surface area for prolonged filter life, ensuring maximum capacity (up to 6 months, depending on usage and quality of incoming water). The end caps provide a tight seal to minimize bypass of incoming water, again ensuring optimal performance for clear, purified water. 
The Neo-Pure 20" x 4.5" filter is directly compatible with the AP810-2 filter. Neo-Pure prides itself in superior quality of construction, and is proud to offer a low-cost alternative to national brands with no sacrifice to efficiency.
