It pairs with the corresponding outer filter (6473-452S) and works with Sundance SPAPURITY mineral sanitizer to reduce debris, oils, and microscopic contaminants. Lightweight and simple to swap, the inner filter focuses on trapping the smallest solids so the mechanical filtration does more of the heavy lifting before chemical sanitizers work.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the MicroClean Ultra II inner filter improve water clarity?\u003c\/h3\u003e\n\u003cp\u003eThe inner filter is made from spun-bound microfiber that captures particles far smaller than standard pleated media.
