Excelpure cartridges are manufactured from 100% pure polypropylene and are sized for use in Big Blue® filter housings. The dual cartridges are designed for purity and will not impart taste, odor or color to the liquid being filtered. Additionally, the polypropylene construction provides superior chemical resistance and is not prone to bacterial attack. The Explore dual cartridges advanced design combines selective “final filtration” with appropriate “pre-filtration” to achieve up to three times the dirt holding capacity of similar size sediment cartridges and many more times that of standard spun or string-wound cartridges. This performance enhancement is achieved by combining two separate gradient layers in one filter. The larger diameter of the pre-filter reduces the particle load to the post filter, allowing it to operate at higher velocities. The effective filter depth is increased to a full 233% of standard spun-polypropylene or string-wound filters. This increased depth provides for very high particulate reduction efficiencies and added loading capacity. The Excelpure dual cartridge is an excellent choice for all residential, rural, municipal
