A pleated water filter is a cartridge made from folded filter media, which packs far more surface area into the same size cartridge than a standard depth filter. That extra surface area gives pleated filters lower pressure drop and higher flow rates, making them a strong choice for whole house filtration and other applications where flow matters. Most pleated filters are sediment filters, and this collection includes pleated sediment filters from trusted brands such as Pentair Pentek and Harmsco, made from cellulose polyester blends (such as the Pentek ECP series) and polyester (such as the Pentek R series), which can often be rinsed and reused. It also includes carbon impregnated pleated filters, such as the Pentek C1 and NCP, which combine sediment filtration with chlorine taste and odour reduction in a single cartridge. Pleated cartridges are available in a range of micron ratings, including 1 micron absolute options, in standard 2.5" x 10" and 2.5" x 20" sizes as well as 4.5" x 10" and 4.5" x 20" Big Blue sizes.
When choosing a pleated water filter, consider your housing size, the micron rating you need, and whether you also want chlorine reduction. Pleated cartridges capture particles mainly on their surface, so where sediment loads are high, a depth style spun poly filter is usually the better choice, either on its own or as a pre-filter. For stronger chlorine, taste and odour reduction, a dedicated carbon block or granular activated carbon (GAC) filter will outperform a carbon impregnated pleated cartridge. Pleated filters should be replaced or cleaned when water pressure noticeably drops.
