Because the inner and outer elements work together as a single filtration stage in the S8M150 tank, replacing them as a matched pack — rather than swapping just one — keeps rated filtration area and flow consistent.\u003c\/p\u003e\n\u003c!-- wft:processed:manual:2026-07-20 --\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":54309090263315,"sku":"170147","price":792.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0920\/0687\/5411\/files\/sta-rite-mod-media-replacement-cartridge-set-for-s8m150-170147-6.webp?v=1784588954","url":"https:\/\/poolaroo.com\/products\/pentair_170147","provider":"Poolaroo","version":"1.0","type":"link"}
