The Darlly PP1644 filter cartridge is designed for compatible filtration applications and features 4-3/16 inch top and bottom openings, a 5-5/8 inch diameter, and an 18-3/4 inch length. Even without square footage noted in the product title, this cartridge is clearly a dimension-driven replacement intended for systems that rely on these exact measurements.
Some filter replacements are chosen less by broad capacity labels and more by the physical fit required by the housing. In those cases, precise top and bottom opening size, diameter, and overall length become the deciding factors. This Darlly cartridge is especially useful where the original element uses matching 4-3/16 inch openings and a slimmer body profile.
The PP1644 is a practical option for buyers who need a fit-specific replacement and want a cartridge designed around clearly defined physical dimensions rather than a generic approximation.
