Hose the modules down from top to bottom at a 45-degree angle when you clean them, and never use a pressure washer — it damages the pleats.\u003c\/p\u003e\n\u003ch3\u003ePRODUCT FEATURES \u0026amp; SPECIFICATIONS:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Pentair Sta-Rite\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMPN:\u003c\/strong\u003e 170146\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Pool \u0026amp; Spa Filter Cartridges\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart:\u003c\/strong\u003e Inner and outer replacement cartridge pack\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Sta-Rite System 3 Modular Media filter S7M400 (21 in filter)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFilter Area:\u003c\/strong\u003e 400 sq ft total\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContents:\u003c\/strong\u003e Large cartridge 25022-0224S (264 sq ft) and small cartridge 25021-0223S (136 sq ft)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCross-Reference:\u003c\/strong\u003e 25022-0224S, 25021-0223S\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 33 lb\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFREQUENTLY ASKED QUESTIONS:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWhich filter does the Pentair 170146 cartridge pack fit?\u003c\/strong\u003e The Pentair 170146 fits the Sta-Rite System 3 Modular Media S7M400 filter, the 21 in filter model rated at 400 sq ft.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWhat is included in the Pentair 170146 pack?\u003c\/strong\u003e The Pentair 170146 pack includes both S7M400 modules: the large outer cartridge 25022-0224S and the small inner cartridge 25021-0223S.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCan I replace just one module instead of the whole 170146 pack?\u003c\/strong\u003e The two modules are also sold individually as 25022-0224S and 25021-0223S, but the 170146 pack replaces both together so the full 400 sq ft of media is renewed at once.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWHY SHOP WITH AL'S COOL POOL STORE?:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e✅ Fast, reliable shipping on every order\u003c\/li\u003e\n\u003cli\u003e✅ Genuine OEM and top-brand parts only\u003c\/li\u003e\n\u003cli\u003e✅ Knowledgeable pool \u0026amp; spa experts ready to help\u003c\/li\u003e\n\u003cli\u003e✅ Hassle-free returns and satisfaction guarantee\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":46459403829383,"sku":"170146","price":849.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0634\/1217\/4983\/files\/pentair-sta-rite-system-3-s7m400-cartridge-pack-170146-complete.jpg?v=1794096362","url":"https:\/\/alscoolpoolstore.com\/products\/pentair-sta-rite-system-3-s7m400-cartridge-pack-170146","provider":"Al's Cool Pool Store","version":"1.0","type":"link"}
