{"type":"firestarter.listing","listing":{"id":"lst_jXRn9C-7","product_name":"Cryospring - All-In-One Chiller Filters","category":"Cold Plunge Filter","description":"\n\nPleated design for longer service life: Pleated cartridges have significantly more surface area than flat cartridges in the same physical size — more filtration capacity before clogging, longer time between replacements, and better maintained water clarity over the life of each cartridge.\n\n50-micron nominal filtration: Captures particulates down to 50 microns for clear water — appropriate for the cold plunge environment where filtration frequency is a real ongoing cost and maintenance consideration.\n\nStandard 10 x 2.5-inch cartridge size: Fits most cold plunge chiller systems that use this standard cartridge size. Verify your chiller's filter specification before ordering — not compatible with the Barton Cold Tub.\n\nFree shipping to the lower 48 states: No shipping charges for the contiguous United States.\n","images":["https://cdn.shopify.com/s/files/1/0508/3670/1334/files/filter2.jpg?v=1780604351","https://cdn.shopify.com/s/files/1/0508/3670/1334/files/filter1.jpg?v=1780604351"],"price":59,"currency":"USD","in_stock":true,"inventory_qty":19998,"dynamic_pricing":false,"listed_at":"2026-06-20T14:56:55.641Z"},"share_url":"https://firestarter.network/l/lst_jXRn9C-7","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
