The Darlly 81502 filter cartridge is made for compatible filtration systems requiring 150 square feet of media area in a slightly slimmer 8-15/16 inch diameter profile. With 4 inch top and bottom openings and a length of 23-5/16 inches, it is a strong choice when a system calls for generous filtration capacity without the broader body used by some larger cartridges.
Matching cartridge size correctly is one of the most important steps in filter maintenance. A cartridge that is close but not exact can create installation headaches, uneven seating, or poor system performance. This model offers a practical balance of higher media area and tighter body dimensions, helping restore filtration efficiency while preserving the intended fit of the housing.
This Darlly cartridge is especially appealing for owners and service professionals who need 150 square feet of capacity in a more moderate cartridge diameter. It is a purposeful fit-driven replacement rather than a one-size-fits-all option.
