Ft.","description":"\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe Unicel C-4621 is a 25 square foot leaf canister replacement cartridge engineered to tackle some of the most stubborn pool contaminants — including plaster dust residue, sand, and fine debris left behind by swimmers and leaf blowers. Designed for compatibility with most major leaf canister brands including Hayward, Rainbow, and Swimables, this cartridge is a reliable, drop-in solution that requires no special modifications or adapters. Built from a heavy-duty 6-ounce filter media, the C-4621 offers superior particle capture compared to standard-weight cartridges, making it especially well-suited for newly plastered pools or high-debris environments. One of the standout advantages of the C-4621 is its environmentally friendly, cleanable, and reusable design — simply rinse and reinstall to extend the service life of the cartridge and reduce waste. Proudly made in the USA, this Unicel cartridge reflects the brand's commitment to quality manufacturing and dependable pool filtration performance.\u003c\/p\u003e\n\u003ch3 class=\"text-text-100 mt-2 -mb-1 text-base font-bold\"\u003eHighlights\u003c\/h3\u003e\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eHeavy-Duty 6-Ounce Filter Media:\u003c\/strong\u003e Constructed with a 6-ounce media weight — heavier than standard cartridge options — the C-4621 delivers enhanced filtration performance, effectively capturing fine particles like plaster dust, sand, and other debris that lighter media may miss.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003e25 Sq.
